Subject: staging: iio: Drop ADIS16060 driver from staging

This part has been declared "not for new designs". It is now
difficult to obtain and we have had no-one come forward with hardware
making it difficult to proceed with the necessary work to move this
driver out of staging.

The device uses two separate chip selects and would require locking
between them which is thought to be difficult to enforce without
non trivial changes in the SPI subsystem.  This work simply isn't worth
doing given the status of the part and the fact no one seems to have
gone for a similar hardware design since this one.

If anyone does have access to one of these and is willing to contribute
the time necessary then we can reevaluate dropping the driver.

Subject: staging: speakup: refactor synths array to use a list

The synths[] array is a collection of synths acting like a list.
There is no need for synths to be an array, so refactor synths[] to use
standard kernel list_head API, instead, and modify the usages to suit.
As a side-effect, the maximum number of synths has also become redundant.

Subject: staging: mt7621-pci: use rt_sysc_?32() to access system-control
 register.

This driver currently has internal knowledge ofthe address
of system-control registers and accesses them by dereferencing
a constant pointer.

It is cleaner to use rt_sysc_r32(), rt_sysc_w32(), rt_sysc_m32()
which is a more standard interface.
So change the defined names to offsets instead of pointers,
and use these functions.

From bf732c6bff5b5767a1c2ec6495dccd76d71c05eb Mon Sep 17 00:00:00 2001
From: NeilBrown <neil@brown.name>
Date: Thu, 7 Jun 2018 08:04:21 +1000
Subject: staging: mt7621-spi: revised half-duplex message handling

The mt7621 SPI engine has a 32 byte buffer and the driver
currently only allows 32-byte read requests and 36 bytes writes
(there is a 4byte op/addr buffer).

This is an unnecessary limitation.  As the SPI clock is controlled
by the host it is quite acceptable to send a larger message in
multiple smaller transactions.  As long as Chip Select is kept asserted
the whole time, the SPI engine can be run multiple times for
a single SPI message.

This patch factors out the transaction logic and calls for each
transfer in the message.  A write transfer might leave bytes in the
buffer to be combined with a following read transfer, as this is
a common pattern.

With this in place, we can remove the current max_transfer_size limit.

In testing, this increases the read throughput for a NOR flash chip
from 1.4MB/s to 2.3MB/s, a 50% improvement.

Subject: staging: mt7621-dts: correct various clock frequencies.

The MT7621 documentation says that the sys clock - also known
as OCP clock for the Open Core Protocol - can be configured to
1/3 or 1/4 of the CPU clock.
Testing on my hardware, using the fact that the SPI clock is
based on the OCP clock and measuring transfer rates, shows
a clock of a little over 200MHz with a CPU clock of 900MHz.
So assume 1/4 is the default.

Also, the nor-flash in the gbpc1 is documented as accepting 50MHz
for request requests, and higher for other requests.  So set
maximum to 50MHz.

Subject: staging: pi433: fix race condition in pi433_ioctl

In the PI433_IOC_WR_TX_CFG case in pi433_ioctl, instance->tx_cfg is
modified via

copy_from_user(&instance->tx_cfg, argp, sizeof(struct pi433_tx_cfg)))

without any kind of synchronization. In the case where two threads
would execute this same command concurrently the tx_cfg field might
enter in an inconsistent state.

Additionally: if ioctl(PI433_IOC_WR_TX_CFG) and write() execute
concurrently the tx config might be modified while it is being
copied to the fifo, resulting in potential data corruption.

Fix: Get instance->tx_cfg_lock before modifying tx config in the
PI433_IOC_WR_TX_CFG case in pi433_ioctl.

Also, do not copy data directly from user space to instance->tx_cfg.
Instead use a temporary buffer allowing future checks for correctness
of copied data and simpler code.

Subject: staging: rts5208: add error handling into rtsx_probe

If rtsx_probe() fails to allocate dev->chip, then release_everything()
will crash on uninitialized dev->cmnd_ready complete.

Patch adds error handling into rtsx_probe.

Subject: staging: wilc1000: use list_head to maintain 'txq_entry_t' elements
 of tx queue

Use list_head data structure for the doubly linked list instead of own
implementation.
Only 'txq_head' is required, so removed the txq_tail pointer from
'wilc' structure.

Following functions are modified to provide data using list_head API's
wilc_wlan_txq_remove()
wilc_wlan_txq_remove_from_head()
wilc_wlan_txq_add_to_tail()
wilc_wlan_txq_add_to_head()
wilc_wlan_txq_get_first()

Subject: staging: wilc1000: use list_head to maintain 'rxq_entry_t elements in
 rx queue

Make use of 'list_head' data structure to maintain the rx buffer queue.
Modified wilc_wlan_rxq_add() to add the element at the tail by using
list_head API and wilc_wlan_rxq_remove() to remove the element from
head.

The pointers vchiq_dbg_dir and vchiq_dbg_clients are local to the

Cleans up sparse warnings:
warning: symbol 'vchiq_dbg_dir' was not declared. Should it be static?
warning: symbol 'vchiq_dbg_clients' was not declared. Should it be static?

Subject: staging: rtl8723bs: drop test

The test selects between two identical values, so it doesn't look useful.
It turns out that the tested expression can only be true anyway, so drop
the test, the corresponding parameter, and the corresponding argument at
the only call site.

The semantic match that finds this problem is as follows:

The buffer_status field is interrupt updated. After every read request,
the buffer_status read field should be reset so that on the next loop

device is ready.

Safe also for 16 bit. and remove declaration of bits variable not needed.

Subject: staging: rtl8188eu: Fix a possible sleep-in-atomic-context bug in
 rtw_disassoc_cmd()

The driver may sleep with holding a spinlock.
The function call paths (from bottom to top) in Linux-4.16.7 are:

[FUNC] kzalloc(GFP_KERNEL)
drivers/staging/rtl8188eu/core/rtw_cmd.c, 502:
		kzalloc in rtw_disassoc_cmd
drivers/staging/rtl8188eu/core/rtw_ioctl_set.c, 256:
		rtw_disassoc_cmd in rtw_set_802_11_ssid
drivers/staging/rtl8188eu/core/rtw_ioctl_set.c, 235:
		spin_lock_bh in rtw_set_802_11_ssid

[FUNC] kzalloc(GFP_KERNEL)
drivers/staging/rtl8188eu/core/rtw_cmd.c, 502:
		kzalloc in rtw_disassoc_cmd
drivers/staging/rtl8188eu/core/rtw_ioctl_set.c, 352:
		rtw_disassoc_cmd in rtw_set_802_11_infrastructure_mode
drivers/staging/rtl8188eu/core/rtw_ioctl_set.c, 336:
		spin_lock_bh in rtw_set_802_11_infrastructure_mode

To fix this bug, GFP_KERNEL is replaced with GFP_ATOMIC.

This bug is found by my static analysis tool (DSAC-2) and checked by
my code review.

Subject: staging: rtl8192u: Truncate block comments to 80 character length -
 Style

Where possible truncation of block comments to the 80 character length
preferred by the coding style.

In a previous version of this commit some of the comments were contentious so
those have not been touched in this version.

Subject: staging: mt7621-pinctrl: add SPDX identifier

It's good to have SPDX identifiers in driver files to make it easier to
audit the kernel tree for correct licenses.

Fix up the one of staging mt7621-pinctrl file to have a proper SPDX
identifier, based on the license text in the file itself. The SPDX
identifier is a legally binding shorthand, which can be used instead of
the full boiler plate text.

This commit replaces all 'unsigned' type declarations along
the driver code in favour of the preferred one 'unsigned int'.
This also silence checkpatch script warnings about this issue.

Current code has structures for all the registers of the device, but
these are never used and there are also masks for all of them, so
these structures do not contain any useful information.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

The driver currently only uses DMA linked mode and the upstream
driver does the same, so remove the basic mode code.

Subject: staging: mt7621-mmc: Refactor dma setup process
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Current code uses two functions for dma setup, msdc_dma_config and
msdc_dma_setup. By now msdc_dma_setup is nearly empty and mainly calls
msdc_dma_config, so the later one can be inline into the first
one. While doing this there is also some refactoring done.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The BUG_ON() removed by this patch is just a duplicate of a prior
BUG_ON() statement. There the condition is just clearer, it checks
weather sglen > MAX_BD_NUM and MAX_BD_NUM is equal MAX_BD_PER_GPD. So
this statement can be safely removed.

Subject: staging: mt7621-mmc: Make msdc_clr_fifo a function and relax cpu
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In the current code, msdc_clr_fifo is a macro and just busy waits for
a limited amount of time for the fifo clear to finish. That is not
correct, the programming manual hits, that the user should wait until
the bit is cleared by hardware and not a limited amount of time.

So the code is changed to a function, that also relaxes the cpu while
busy waiting.

From 2dfc73d5bb908e38789c715de1aceeae0fb2f4b9 Mon Sep 17 00:00:00 2001

Subject: staging: mt7621-mmc: Cleanup source of base address for io
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently the base address for all io operations is hidden behind a
macro, REG_ADD. This macro uses the symbol "base" as the base address
and all functions set base = host->base. This is hard to read, so the
whole wrapping is removed and host->base is directly inserted in the
io access.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The response type of the MMC_SEND_OP_COND command is correctly
determined using the mmc_resp_type macro, because the only use of that
opcode, mmc_send_op_cond, correctly places MMC_RSP_R3 in cmd.flags.

So there is no need to treat that opcode separately.

Subject: staging: mt7621-gpio: make use 'bgpio_init' from GPIO_GENERIC

Gpio complexity is just masking the fact that offset is always
0..n and writes to bits 0..n of some memory address. Because
of this whole thing can just me converted to use GPIO_GENERIC
and avoid duplications of a lot of driver custom functions.
So use bgpio_init instead of custom code adding GPIO_GENERIC
dependency to the Kconfig file. Also to make easier using
bgpio_init function offset for each gpio bank, enumeration
where register were defined has been replaced in favour of
some macros which handle each gpio offset taking into account
the bank where are located. Because of this change write and
read functions which are being used for remaining irq handling
stuff have been updated also as well as its dependencies along
the code.

'builtin_platform_driver' which seems to be the correct one.

Subject: staging: mt7621-gpio: implement '.irq_[request|release]_resources'
 functions

When implementing custom irqchips it is important to also
implement .irq_request_resources() and .irq_release_resources()
and make sure these call gpiochip_[un]lock_as_irq().
Add those two for this driver. Also store struct device pointer
in global state structure to be able to use 'dev_err' with the
device from 'mediatek_request_resources' function.

Subject: staging: mt7621-gpio: avoid custom irq_domain for gpio

Instead of create a custom irq_domain for this chip, use
'gpiochip_set_chained_irqchip' from GPIOLIB_IRQCHIP. It
is ok to call this function several times. We have to
manually mark the line with 'IRQF_SHARED' and then loop
over the three banks until you find a hit. There were
some problems with removing an irqchip like that but this
driver is a bool so it might work just fine. After this
changes the functions 'mediatek_gpio_to_irq' is not needed
anymore and also the 'gpio_irq_domain' field from the state
container. Instead of use the custom irq domain in the irq
handler use the associated domain from the gpio_chip in
'irq_find_mapping' function. Function 'mediatek_gpio_bank_probe'
has been moved a it to the botton to have all the irq related
functions together and avoid some forward declarations to resolve
some symbols along the code.

Subject: staging: mt7621-gpio: remove no more necessary PIN_MASK macro

PIN_MASK macro was being used because of the fact we were only
using one interrupt controller for all of the gpio chips. This
has been changed to use one per gpio chip and each has 32 irqs.
Because of this this macro is not needed anymore. Use BIT macro
instead.

Subject: staging: mt7621-gpio: avoid one level indentation in interrupt
 handler

There is no need to check for 'pending' before loop over the
interrupts using 'for_each_set_bit' if nothing is set the
return values will be the same so just avoid this check avoiding
also one level intentation and improving readability.

Subject: staging: mt7621-gpio: set different names for each gpio_chip and
 irq_chip

Currently the driver defines 3 gpiochips, one for each bank.

/sys/class/gpio/gpiochip416/label:1e000600.gpio
/sys/class/gpio/gpiochip448/label:1e000600.gpio
/sys/class/gpio/gpiochip480/label:1e000600.gpio

Unfortunately they all have the same label

Interrupts from /proc/interrupt show the same name which is
confusing:

/proc/interrupts:

17: 0  0  0  0  MIPS GIC  19  mt7621, mt7621, mt7621

which is the interrupt from the GPIO controller.
It is a little weird that all three banks are named "mt7621"
here. We also have:

26: 0  0  0  0  GPIO  18  reset

which is the interrupt from GPIO which provides the "reset"
button. I suspect that if I had interrupts form two different
banks they would both be called "GPIO" which would be a little
confusing.

In order to unify all of this set different names for each chip
Use a 'bank-based' name instead the same for all: 'mt7621-bank[0-2]'.
Create a new 'mediatek_gpio_bank_name' function which return the
name depending on the bank number. This function is allways called
with a valid index 0, 1 or 2.

Banks shouldn't be defined in DT if number of resources

has three banks so take that into account in order to don't
overspecify the device tree. Device tree will only have one
node making it simple. Update device tree, binding doc and

Subject: staging: wilc1000: Use common structs to parse ip packets

Use structs ethhdr, iphdr and tcphdr instead of manual parsing in
tcp_process.
This commit fix handling of ip packets containing options.
It also fixes the following sparse warning:

Subject: staging: wilc1000: remove host_if_work() to handle TODO list issue

Remove multiplexing of command at host_if_work().
Make use of function pointer instead of command ID to track individual
work_struct separately.

Modified the handler function to take work_struct pointer as argument
and its return type is changes to void. Now prototype of 'handle_'
function is same work_struct i.e. 'void (*fun)(struct struct *)' to
register with work_queue.
Removed host_if_work() because its not required now.

Subject: staging: wilc1000: remove unused marco related to HIF commands

After removing the multiplexing of hif commands in hif_if_work()
macros prefix with 'HOST_IF_MSG_' are not required. Also 'id' field in
host_if_msg is not required anymore.

Subject: staging: wilc1000: move the allocation of cmd out of
 wilc_enqueue_cmd()

Instead of allocating the host_if_cmd in wilc_enqueue_cmd() now moved
the allocation of cmd in the caller. Added the NULL check for
'hif_workqueue' before posting the work queue in wilc_enqueue_cmd().

From 5e6f8a8ae2923e0f9a8425320d5edb490a73abf0 Mon Sep 17 00:00:00 2001
From: Ajay Singh <ajay.kathat@microchip.com>
Date: Tue, 26 Jun 2018 11:37:06 +0530
Subject: staging: wilc1000: added 'work_comp' completion as part of
 host_if_msg

Added 'work_comp' completion in 'host_if_msg'. It allows handling the
sync call to wait for sepecific completion event.
The commands can be run in sync way waiting for their specific
completion event.
Added is_sync flag in wilc_create_work_queue() to handle the sync call to
host interface.

After adding completion as part of host_if_msg now
below completion are not required
 comp_test_key_block;
 comp_test_disconn_block
 comp_get_rssi
 comp_inactive_time
 hif_wait_response

Modified wilc_get_statistics() API to handle get statistic in sync &
async way.

Subject: staging: wilc1000: rename wilc_enqueue_cmd() to wilc_enqueue_work()

Rename wilc_enqueue_cmd() to wilc_enqueue_work() because its used to
enqueue the work queue. Also removed the function header comment for
wilc_enqueue_cmd() as its not correct.

Subject: staging: wilc1000: handle freeing of key data in wep add key

Modified the code to free the allocated memory, used to store the key in
wilc_add_wep_key_bss_sta() and wilc_add_wep_key_bss_ap().
After work completion notification is received, free the
memory allocated to avoid missing of free in work function.

[1]. Move handling for each individual members of 'union message_body' out
into a separate 'struct work_struct' and completely remove the
multiplexerthat is currently part of host_if_work(), allowing movement
of the implementation of each message handler into the callsite of the
function that currently queues the 'host_if_msg'.

Subject: staging: android: ashmem: Fix mmap size validation

The ashmem driver did not check that the size/offset of the vma passed
to its .mmap() function was not larger than the ashmem object being
mapped. This could cause mmap() to succeed, even though accessing parts
of the mapping would later fail with a segmentation fault.

Ensure an error is returned by the ashmem_mmap() function if the vma
size is larger than the ashmem object size. This enables safer handling
of the problem in userspace.

Subject: staging: pi433: fix race condition in pi433_open

The device structure contains a useless non-atomic users counter which
is subject to race conditions. It has probably been created to handle
the case where remove is executed while operations are still executing
on open fds but this will never happen because of reference counts.

Drop the users counter and move rx buffer {de,}allocation to probe()
and remove(). Remove associated dead code from open() and release().
Remove related TODO entry from ioctl().

Subject: staging: rtl8723bs: Move rate section index lookup to new function.

The rate section lookup is a large switch statement in the middle of
'phy_get_tx_pwr_lmt()'; refactor this statement into it's own function
for increased readability.

Subject: staging: rtl8723bs: remove get_monotonic_boottime()

get_monotonic_boottime() is deprecated because it uses the
old 'timespec' structure. This replaces one of the last callers
with a call to ktime_get_boottime, which also simplifies it
a bit by avoiding a double conversion.

Subject: staging: rtl8723bs: Fix two possible sleep-in-atomic-context bugs in
 translate_scan()

The driver may sleep with holding a spinlock.
The function call paths (from bottom to top) in Linux-4.16.7 are:

[FUNC] kzalloc(GFP_KERNEL)
drivers/staging/rtl8723bs/os_dep/ioctl_linux.c, 323:
		kzalloc in translate_scan
drivers/staging/rtl8723bs/os_dep/ioctl_linux.c, 1554:
		translate_scan in rtw_wx_get_scan
drivers/staging/rtl8723bs/os_dep/ioctl_linux.c, 1533:
		spin_lock_bh in rtw_wx_get_scan

[FUNC] kzalloc(GFP_KERNEL)
drivers/staging/rtl8723bs/os_dep/ioctl_linux.c, 455:
		kzalloc in translate_scan
drivers/staging/rtl8723bs/os_dep/ioctl_linux.c, 1554:
		translate_scan in rtw_wx_get_scan
drivers/staging/rtl8723bs/os_dep/ioctl_linux.c, 1533:
		spin_lock_bh in rtw_wx_get_scan

To fix these bugs, GFP_KERNEL is replaced with GFP_ATOMIC.

These bugs are found by my static analysis tool (DSAC-2) and checked by
my code review.

Subject: staging: use BIT_ULL for NL80211_STA_INFO_* attribute types

The BIT macro uses unsigned long which some architectures handle as 32 bit
and therefore might cause macro's shift to overflow when used on a value
equals or larger than 32 (NL80211_STA_INFO_RX_DURATION and afterwards).

Since 'filled' member in station_info changed to u64, BIT_ULL macro
should be used with all NL80211_STA_INFO_* attribute types instead of BIT
to prevent future possible bugs when one will use BIT macro for higher
attributes by mistake.

This commit cleans up all usages of BIT macro with the above field
in cfg80211 by changing it to BIT_ULL instead.

Subject: staging: rtsx: remove rtsx_trace() and related code

The driver has rather excessive amount of tracing code, which would be
better done using ftrace. This is obviously not a main feature of the
driver, and it should work just as well without it.

Removing it saves over 1300 lines of code and likely makes the driver
a bit faster by avoiding lots of calls into the timekeeping code.

I came across this while cleaning up the last users of the deprecated
getnstimeofday64() function, of which there is one in the now-removed
get_current_time() function of the rtsx driver that was only used for
tracing.

Subject: staging: rtlwifi: Fix a possible sleep-in-atomic-context bug in
 _is_fw_read_cmd_down()

The driver may sleep with holding a spinlock.
The function call path (from bottom to top) in Linux-4.16.7 is:

[FUNC] schedule
drivers/staging/rtlwifi/halmac/rtl_halmac.c, 884:
		schedule in _is_fw_read_cmd_down
drivers/staging/rtlwifi/halmac/rtl_halmac.c, 912:
		_is_fw_read_cmd_down in rtl_halmac_send_h2c
drivers/staging/rtlwifi/halmac/rtl_halmac.c, 907:
		_raw_spin_lock_irqsave in rtl_halmac_send_h2c

To fix this bug, schedule() is replaced with mdelay(1).

This bug is found by my static analysis tool (DSAC-2) and checked by
my code review.

Subject: staging: wlan-ng: replace WLAN_CTL_FRAMELEN with inline function in
 p80211hdr.h

checkpatch reports a "CHECK" diagnostic for WLAN_CTL_FRAMELEN as the
macro reuses its argument, leading to possible side-effects. Avoid
this by replacing the macro with an equivalent function, named
wlan_ctl_framelen (as recommended in the coding style). All references
to the macro also updated accordingly.

Subject: staging: rtl8723bs: refactor rtw_macaddr_cfg()

Using is_broadcast_ether_addr() and is_zero_ether_addr() instead of
testing each byte of the mac[] array for 0xff and 0x00 shortens the
code and improves readability.

If np == NULL, of_get_property() returns NULL, hence the "np" check
is not needed.

Instead of a fixed default mac address use a random one to reduce the
likelihood of mac address collision.

Thanks to Joe Perches and Dan Carpenter.

Subject: staging: rtl8723bs: use mac_pton() in rtw_macaddr_cfg()

Use the mac_pton() helper to convert the mac address string.

The functions key_char2num() and key_2char2num() are not used
anywhere else and can be removed.

This also has the benefit of validating the input since mac_pton()
returns false if the string is not valid.

Subject: staging/skein: Remove Skein and Threefish code

It's been four years since this was added.  In the interim, skein has
not seen any mainstream adoption.  Same with the threefish block cipher
upon which it's based.

In the discussion over which hash algorithm will replace SHA1 in git,
it's not one of the contenders.

There's absolutely no reason to think that there is anything wrong with
Skein or Threefish.  The only reason for this removal is a lack of
adoption.

If a real user comes forward, I'd be happy to assist with integrating
this code into mainline.

-/**
- * @file skein_api.h
- * @brief A Skein API and its functions.
- * @{
- *
- * This API and the functions that implement this API simplify the usage
- * of Skein. The design and the way to use the functions follow the openSSL
- * design but at the same time take care of some Skein specific behaviour
- * and possibilities.
- *
- * The functions enable applications to create a normal Skein hashes and
- * message authentication codes (MAC).
- *
- * Using these functions is simple and straight forward:
- *
- * @code
- *
- * #include "skein_api.h"
- *
- * ...
- * struct skein_ctx ctx;             // a Skein hash or MAC context
- *
- * // prepare context, here for a Skein with a state size of 512 bits.
- * skein_ctx_prepare(&ctx, SKEIN_512);
- *
- * // Initialize the context to set the requested hash length in bits
- * // here request a output hash size of 31 bits (Skein supports variable
- * // output sizes even very strange sizes)
- * skein_init(&ctx, 31);
- *
- * // Now update Skein with any number of message bits. A function that
- * // takes a number of bytes is also available.
- * skein_update_bits(&ctx, message, msg_length);
- *
- * // Now get the result of the Skein hash. The output buffer must be
- * // large enough to hold the request number of output bits. The application
- * // may now extract the bits.
- * skein_final(&ctx, result);
- * ...
- * @endcode
- *
- * An application may use @c skein_reset to reset a Skein context and use
- * it for creation of another hash with the same Skein state size and output
- * bit length. In this case the API implementation restores some internal
- * internal state data and saves a full Skein initialization round.
- *
- * To create a MAC the application just uses @c skein_mac_init instead of
- * @c skein_init. All other functions calls remain the same.

- * @brief A Threefish cipher API and its functions.
- * @{
- *
- * This API and the functions that implement this API simplify the usage
- * of the Threefish cipher. The design and the way to use the functions
- * follow the openSSL design but at the same time take care of some Threefish
- * specific behaviour and possibilities.
- *
- * These are the low level functions that deal with Threefish blocks only.
- * Implementations for cipher modes such as ECB, CFB, or CBC may use these
- * functions.
- *

-	threefish_set_key(&key_ctx, THREEFISH_512, key, tweak);

From 9a69f5087ccc20bb411025decab455836df04168 Mon Sep 17 00:00:00 2001
From: Simon Que <sque@chromium.org>

Subject: drivers/staging: Gasket driver framework + Apex driver

The Gasket (Google ASIC Software, Kernel Extensions, and Tools) kernel
framework is a generic, flexible system that supports thin kernel
drivers. Gasket kernel drivers are expected to handle opening and
closing devices, mmap'ing BAR space as requested, a small selection of
ioctls, and handling page table translation (covered below). Any other
functions should be handled by userspace code.

The Gasket common module is not enough to run a device. In order to
customize the Gasket code for a given piece of hardware, a device
specific module must be created. At a minimum, this module must define a
struct gasket_driver_desc containing the device-specific data for use by
the framework; in addition, the module must declare an __init function
that calls gasket_register_device with the module's gasket_driver_desc
struct. Finally, the driver must define an exit function that calls
gasket_unregister_device with the module's gasket_driver_desc struct.

One of the core assumptions of the Gasket framework is that precisely
one process is allowed to have an open write handle to the device node
at any given time. (That process may, once it has one write handle, open
any number of additional write handles.) This is accomplished by
tracking open and close data for each driver instance.

+This is a list of things that need to be done to get this driver out of the
+staging directory.
+- Use SPDX tags to show the license of the file, and no more "boiler-plate"
+  license text is needed.
+- Remove static function declarations.
+- Document sysfs files with Documentation/ABI/ entries.
+- Use misc interface instead of major number for driver version description.
+- Add descriptions of module_param's
+- Remove gasket-specific logging functions.
+- apex_get_status() should actually check status.
+- Static functions don't need kernel doc formatting, can be simplified.
+- Fix multi-line alignment formatting to look like:
+      int ret = long_function_name(device, VARIABLE1, VARIABLE2,
+                                   VARIABLE3, VARIABLE4);
+- "drivers" should never be dealing with "raw" sysfs calls or mess around with
+  kobjects at all. The driver core should handle all of this for you
+  automaically. There should not be a need for raw attribute macros.

Subject: staging: speakup: Replace strncpy with memcpy

gcc 8.1.0 generates the following warnings.

drivers/staging/speakup/kobjects.c: In function 'punc_store':
drivers/staging/speakup/kobjects.c:522:2: warning:
	'strncpy' output truncated before terminating nul
	copying as many bytes from a string as its length
drivers/staging/speakup/kobjects.c:504:6: note: length computed here

drivers/staging/speakup/kobjects.c: In function 'synth_store':
drivers/staging/speakup/kobjects.c:391:2: warning:
	'strncpy' output truncated before terminating nul
	copying as many bytes from a string as its length
drivers/staging/speakup/kobjects.c:388:8: note: length computed here

Using strncpy() is indeed less than perfect since the length of data to
be copied has already been determined with strlen(). Replace strncpy()
with memcpy() to address the warning and optimize the code a little.

Subject: staging: rtl8723bs: remove pointless if else in rtw_sdio_resume()

Whether any of the conditions is true or not, the return variable
is always set to rtw_resume_process(padapter). Replace the if else
construct with a single call to rtw_resume_process(). Also remove
the now unused local variable pwrpriv.

ident at the right place fixes this problem.

The default gpio.of_xlate function assumes there is one gpio chip
for each devicetree node. Device tree had changed to only use one node,
which corresponds to 3 different gpio chips now. For that approach
to work we need a custom xlate function.

Subject: staging: mt7621-gpio: use devm_kasprintf to set gpio banks labels

Instead of using a custom function to return desired name for gpio
use the default assigned one and concat it '-bankN' suffix using
devm_kasprintf kernel function.

Subject: staging: mt7621-pinctrl: refactor rt2880_pinctrl_dt_node_to_map
 function

Using 'function' and 'group' bindings in the device tree give the
posibility of refactor 'rt2880_pinctrl_dt_node_to_map' and simplify
it a lot. Make use of 'for_each_node_with_property' function to count
number of groups for the node and iterate over the groups using
'of_property_for_each_string' calling 'pinctrl_utils_add_map_mux'
function which is the same of the custom function in this driver code
'rt2880_pinctrl_dt_subnode_to_map' which is not needed anymore.

We don't really need initialization of this at such an early stage.
Just use builtin_platform_driver to initialize this driver.

Subject: Staging: Gasket: shift wrapping bug in gasket_read_modify_write_64()

This function only has one caller so mask_width is 1 and mask_shift is
32.  Shifting an int by 32 bits is undefined, but I guess on GCC it
wraps to 0x1?  Anyway it's supposed to be 0x100000000.

Subject: staging: rtl8188eu: refactor rtw_macaddr_cfg()

Use ether_addr_copy() instead of memcpy() to copy the mac address.

Using is_broadcast_ether_addr() and is_zero_ether_addr() instead of
testing each byte of the mac[] array for 0xff and 0x00 shortens the
code and improves readability.

Instead of a fixed default mac address use a random one to reduce the
likelihood of mac address collision.

Subject: staging: fsl-dpaa2/eth: Remove Rx frame size check

Most Ethernet drivers don't enforce the MTU value as upper limit
for ingress frames. We too support receiving frames larger than
MTU, so allow that.

Remove our ndo_change_mtu implementation, letting the default
stack implementation handle things. Also, set the max frame length
allowed by hardware only once at probe time, with the largest
possible value.

Subject: staging: mt7621-pinctrl: init *map to NULL for correct memory
 assignation

pinctrl_utils_reserve_map() calls krealloc() on *map. Because of this
*map need to be initialized to NULL before calling it.

Subject: Revert "staging: mt7621-pinctrl: replace core_initcall_sync with
 builtin_platform_driver"

That patch causes the network interface on the device to stop working.
device_initcall() is called much later than core_initcall_sync() and
that seem to be a problem. Revert it to get a correct behaviour.

-Mediatek MT7621 SoC GPIO controller bindings
-
-The IP core used inside these SoCs has 3 banks of 32 GPIOs each.
-The registers of all the banks are interwoven inside one single IO range.
-We load one GPIO controller instance per bank. Also the GPIO controller can receive
-interrupts on any of the GPIOs, either edge or level. It then interrupts the CPU
-using GIC INT12.
-
-Required properties for the top level node:
-- #gpio-cells : Should be two. The first cell is the GPIO pin number and the
-   second cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>.
-   Only the GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
-- #interrupt-cells : Specifies the number of cells needed to encode an
-   interrupt. Should be 2. The first cell defines the interrupt number,
-   the second encodes the triger flags encoded as described in
-   Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
-- compatible:
-  - "mediatek,mt7621-gpio" for Mediatek controllers
-- reg : Physical base address and length of the controller's registers
-- interrupt-parent : phandle of the parent interrupt controller.
-- interrupts : Interrupt specifier for the controllers interrupt.
-- interrupt-controller : Mark the device node as an interrupt controller.
-- gpio-controller : Marks the device node as a GPIO controller.
-
-Example:
-	gpio@600 {
-		#gpio-cells = <2>;
-		#interrupt-cells = <2>;
-		compatible = "mediatek,mt7621-gpio";
-		gpio-controller;
-		interrupt-controller;
-		reg = <0x600 0x100>;
-		interrupt-parent = <&gic>;
-		interrupts = <GIC_SHARED 12 IRQ_TYPE_LEVEL_HIGH>;

To get config address the same pattern is repeated in some functions
along the code. Factor out a new mt7621_pci_get_cfgaddr for calculate
it and use it in convenient places. Adjust types to match to u32 where
is neccesary.

Subject: staging: pi433: Comply with 80 character column limit

Lines have been split where it makes sense to shorten them in order
to comply with the coding standards and fix checkpatch.pl warnings.
There are still lines left that are too long, however breaking
those would impair readability.

Changes in v2:
 - now working on staging-next branch of the staging tree
 - the changes to the defines previously made are deleted
   due to readability

Subject: staging: pi433: Use preferred commenting style

For multi-line comments, the preferred commenting style from the
coding style Documentation was applied to the comments, meaning
almost blank lines at the beginning and end of the comment.
One changed comment includes a line over 80 characters, causing
checkpatch.pl to complain, however breaking this line would not
make much sense, so it is kept like it is.

Subject: staging: gasket: add SPDX identifiers to all files.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Fix up the all of the staging gasket files to have a proper SPDX
identifier, based on the license text in the file itself.  The SPDX
identifier is a legally binding shorthand, which can be used instead of
the full boiler plate text.

Subject: staging: gasket: remove redundant license information

Now that the SPDX tag is in all gasket files, that identifies the
license in a specific and legally-defined manner.  So the extra GPL text
wording can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

Use strlcpy instead of strncpy to avoid gcc 8 warning:
warning: '__builtin_strncpy' specified bound 16 equals destination size [-Wstringop-truncation]

The maximum length of the source string including terminating null is 5.
Hence it always fits in the destination buffer of length 16.

Subject: staging: bcm2835-audio: Check if workqueue allocation failed

Currently, if allocating a workqueue fails, the driver will probe
successfully but it will silently do nothing, which is rather silly.
So instead bail out with -ENOMEM in bcm2835_audio_open() if
alloc_workqueue() fails, and remove the now pointless checks for a NULL
workqueue.

While at it, get rid of the rather pointless one-line function
my_workqueue_init().

Currently, if bcm2835_audio_open() fails partway, the allocated
workqueue is leaked. Avoid that.

While at it, propagate the return value of
bcm2835_audio_open_connection() on failure instead of returning -1.

Subject: staging:rtl8192u: remove typedef from struct rx_drvinfo_819x_usb

Removed the typedef from the struct rx_drvinfo_819x_usb  to leave it as a
simple structure.

This clears the issue flagged by checkpatch, defining new types.

Subject: staging:rtl8192u: Change struct r8192_priv member Rf_Mode from u8 >
 enum

The file r8192U.h defines the structure for holding private data for the
driver (typedef struct r8192_priv). This structure includes a member Rf_Mode
which is defined to be of type "u8".

Whilst the variable Rf_Mode is defined to be of type "u8" it is being assigned
enumerated values defined by the enumerated type "enum rf_op_type". Because of
the mismatch in types being used any advantage of using an enumerated type, to
have the compiler check assignments, is nullified.

This patch changes the type of the Rf_Mode member from a u8 to the enumerated
type "enum rf_op_type", so that the compiler can now check assignments.

This change of type would cause a problem if the structure was mapped from a
hardware device and the size and location of members was significant. I
believe that the structure to hold private data for the driver is allocated
from memory and populated with data in the function rtl8192_usb_probe() in the
file r8192U_core.c. As such the physical size of the member variable Rf_Mode
is not significant, so the change should have no impact on code execution, bar
the move from a u8 type to an int, (or whatever size compiler uses for enum).

Subject: staging:rtl8192u: remove typedef of enumeration SwChnlCmdID - Style

To clear a checkpatch issue removed the typedef of the enumeration SwChnlCmdID
this should not impact runtime code as it's only a coding style change.

Subject: staging:rtl8192u: remove typedef from structure SwChnlCmd - Style

Checkpatch warns against creation of new types in code. This patch simply
removes the "typedef" declaration of the structure SwChnlCmd to clear this
issue. Simple coding style issue which should not impact runtime execution.

No one calls it, it is claimed to be "legacy", whatever that means, so
just remove the dead code.

Subject: staging: gasket: remove gasket_wait_sync()

This function is not called anywhere, so just remove it.

Also, as an added benifit, Arnd points out that it doesn't even work
properly:
	This code won't work correct during leap seconds or a concurrent
	settimeofday() call, and it probably doesn't do what the author intended
	even for the normal case, as it passes a timeout in nanoseconds but
	reads the time using a jiffies-granularity accessor.

Subject: staging: rtl8188eu: remove is_{multicast,broadcast}_mac_addr

Remove custom is_multicast_mac_addr() and is_broadcast_mac_addr().
Use is_multicast_ether_addr() instead.

By definition the broadcast address is also a multicast address.
is_multicast_ether_addr() returns true for broadcast addresses.
Hence checking for multicast in the conditional is sufficient.

Subject: staging: android: ashmem: Shrink directly through shmem_fallocate

When ashmem_shrink is called from direct reclaim on a user thread, a
call to do_fallocate will check for permissions against the security
policy of that user thread.  It can thus fail by chance if called on a
thread that isn't permitted to modify the relevant ashmem areas.

Because we know that we have a shmem file underneath, call the shmem
implementation of fallocate directly instead of going through the
user-space interface for fallocate.

Subject: staging: gasket: gasket_wait_with_reschedule simplify logic

gasket_wait_with_reschedule() is a little more clear if we just return
directly when the waited-for condition is hit.  This also allows the
following condition check to be removed and identation of the
conditionally-executed code to be reduced.

Subject: staging: rtl8188eu: remove MacAddr_isBcst macro

Use is_broadcast_ether_addr instead of the MacAddr_isBcst macro.
The macro is not used anywhere else, so remove it.

Subject: staging: rtl8188eu: use is_multicast_ether_addr

Use is_multicast_ether_addr instead of IS_MCAST.
By definition the broadcast address is also a multicast address,
so checking for !multicast in the conditional is sufficient.

To clear a checkpatch issue removed the typedef of the enumeration TR_SELECT
this should not impact runtime code as it's only a coding style change.

Subject: staging:rtl8192u: remove typedef of struct TS_COMMON_INFO - Style

To clear a checkpatch issue removed the typedef of the structure
TS_COMMON_INFO.

This change removes the previous declaration, which defined two types, both
TS_COMMON_INFO and a pointer type PTS_COMMON_INFO:

typedef struct _TS_COMMON_INFO {
	...
} TS_COMMON_INFO, *PTS_COMMON_INFO;

The pointer type has been completely removed from the code, as:
"(so-called Hungarian notation) is brain damaged" according to the coding
standard.

Subject: staging:rtl8192u: Rename TSpec > t_spec - Style

Rename the TS_COMMON_INFO structure's member TSpec to t_spec. This change
clears the checkpatch issue with CamelCase naming of variables. There should
be no impact on runtime execution.

Subject: staging: wilc1000: remove extra enums defined for ieee80211_eid

Cleanup patch to make use of existing enum 'ieee80211_eid' instead of
adding new enum in WILC for element ID's.

The below mapping is same to remove extra enum in WILC.

SUPP_RATES_IE   	-> WLAN_EID_SUPP_RATES
EXT_SUPP_RATES_IE	-> WLAN_EID_EXT_SUPP_RATES
HT_CAPABILITY_IE	-> WLAN_EID_HT_CAPABILITY
RSN_IE			-> WLAN_EID_RSN
WPA_IE			-> WLAN_EID_VENDOR_SPECIFIC
WMM_IE			-> WLAN_EID_VENDOR_SPECIFIC
P2P_IE			-> WLAN_EID_VENDOR_SPECIFIC

Also remove enum 'info_element_id' as its same as 'ieee80211_eid', below
the mapping of elements of enums which are used.

ITIM -> WLAN_EID_TIM
IDSPARMS -> WLAN_EID_DS_PARAMS

From: Ajay Singh <ajay.kathat@microchip.com>
Date: Thu, 19 Jul 2018 04:15:17 +0530
Subject: staging: wilc1000: use 'int' inplace of 's32' date type

Pointer 'nic' is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:

Subject: staging: wilc1000: remove gpio parameter from wilc_netdev_init()

Instead of passing the gpio as parameter to wilc_netdev_init() now
setting its value after finishing wilc_netdev_init() call. Avoided

Now making use of descriptor-based interface instead of integer-based
interface for IRQ GPIO.
Added device tree binding reference for WILC SDIO and SPI interface
module. Also moved the code to free gpio descriptor in module remove
as the reference was fetched in probe function.
Updated the TODO file

Subject: staging: rtl8188eu/rtl8723bs: fix character encoding

drivers/staging/rtl8188eu/include/odm.h uses an incorrect encoding
for the '...' character in two comments, which makes it one of the
few non-UTF-8 source files.

This removes the odd characters and uses the same ASCII representation
that we have in the regular rtlwifi driver. The second instance
of drivers/staging/rtl8723bs/hal/odm.h is garbled in a different way,
so I change it to be the same as well even though it is already
plain ASCII.

Subject: staging: bcm2835-camera: handle wait_for_completion_timeout return
 properly

wait_for_completion_timeout returns unsigned long not int so a variable of
proper type is introduced. Further the check for <= 0 is ambiguous and
should be == 0 here indicating timeout.

 wait_for_completion_timeout

wait_for_completion_timeout returns unsigned long not int so a variable of
proper type is introduced. Further the check for <= 0 is ambiguous and should
be == 0 here indicating timeout which is the only error case so no additional

Subject: staging:rtl8192u: Remove unused page 1 definitions - Style

Remove all the "page 1" definitions as they are not used in code.

A lot of these definitions, if not all, fail checkpatch because of
CamelCase issues. Rather then change the names of unused constants
simply remove. This is a coding style change which should have no
impact on runtime execution.

Subject: staging:rtl8192u: Remove unused page 8 definitions - Style

Remove page 8 definitions which are never used in code.

Many of these definitions, if not all, fail the checkpatch CamelCase
checks. To avoid the effort of renaming unused definitions they have
been removed. This is a style change which should have no impact on
runtime execution.

Subject: staging:rtl8192u: Remove unused page-8 Bit Mask definitions - Style

Remove unused 'page-8' Bit Mask definitions. These definitions fail the
checkpatch CamelCase naming test, since they are unused in code they have
simply been removed from code, rather then renamed. This is a coding
style change which should not impact runtime code execution.

Subject: staging:rtl8192u: Remove unused page d Bit Mask definitions - Style

Remove the unused 'page d' Bit Mask definitions. These definitions will
fail the checkpatch CamelCase naming test. Since the definitions are
unused in code they have been removed, rather then renaming.

This is a coding style change which should not impact runtime code
execution.

Subject: staging:rtl8192u: Remove unused Zebra4 bit mask definitions - Style

Remove the unused 'Zebra4' bit mask definitions. These definitions fail
the checkpatch CamelCase naming tests. Rather then renaming, as the
definitions are unused they have simply been removed.

This is a coding style change which should not impact runtime code
execution.

Subject: staging:rtl8192u: Remove typedef of u32 to QOS_MODE - Style

The typedef of QOS_MODE as a u32 is contrary to coding standard and fails
the checkpatch tests for defining new types in code. Definitions of type
QOS_MODE have simply been replaced with a u32 type.

This is a coding style change which should not impact runtime execution.

Subject: staging: add driver for Xilinx AXI-Stream FIFO v4.1 IP core

This IP core has read and write AXI-Stream FIFOs, the contents of which can
be accessed from the AXI4 memory-mapped interface. This is useful for
transferring data from a processor into the FPGA fabric. The driver creates
a character device that can be read/written to with standard
open/read/write/close.

See Xilinx PG080 document for IP details.

https://www.xilinx.com/support/documentation/ip_documentation/axi_fifo_mm_s/v4_1/pg080-axi-fifo-mm-s.pdf

The driver currently supports only store-forward mode with a 32-bit
AXI4 Lite interface. DOES NOT support:
        - cut-through mode
        - AXI4 (non-lite)

+Xilinx AXI-Stream FIFO v4.1 IP core
+
+This IP core has read and write AXI-Stream FIFOs, the contents of which can
+be accessed from the AXI4 memory-mapped interface. This is useful for
+transferring data from a processor into the FPGA fabric. The driver creates
+a character device that can be read/written to with standard
+open/read/write/close.
+
+See Xilinx PG080 document for IP details.
+
+Currently supports only store-forward mode with a 32-bit
+AXI4-Lite interface. DOES NOT support:
+	- cut-through mode
+	- AXI4 (non-lite)
+
+Required properties:
+- compatible: Should be "xlnx,axi-fifo-mm-s-4.1"
+- interrupt-names: Should be "interrupt"
+- interrupt-parent: Should be <&intc>
+- interrupts: Should contain interrupts lines.
+- reg: Should contain registers location and length.
+- xlnx,axi-str-rxd-protocol: Should be "XIL_AXI_STREAM_ETH_DATA"
+- xlnx,axi-str-rxd-tdata-width: Should be <0x20>
+- xlnx,axi-str-txc-protocol: Should be "XIL_AXI_STREAM_ETH_CTRL"
+- xlnx,axi-str-txc-tdata-width: Should be <0x20>
+- xlnx,axi-str-txd-protocol: Should be "XIL_AXI_STREAM_ETH_DATA"
+- xlnx,axi-str-txd-tdata-width: Should be <0x20>
+- xlnx,axis-tdest-width: AXI-Stream TDEST width
+- xlnx,axis-tid-width: AXI-Stream TID width
+- xlnx,axis-tuser-width: AXI-Stream TUSER width
+- xlnx,data-interface-type: Should be <0x0>
+- xlnx,has-axis-tdest: Should be <0x0> (this feature isn't supported)

Subject: staging: fsl-dpaa2/eth: Update default hash key

In our documentation, we claim to use a 5-tuple key for Rx hash
distribution of flows. The code however configures a key composed
of all supported header fields.

Update the Rx hash key to contain only the documented fields:
{IP src, IP dst, IP nextproto, L4 src, L4 dst}, which was the
original intention and makes most sense as a default.

Subject: staging: erofs: add on-disk layout

This commit adds the on-disk layout header file of erofs.

Note that the on-disk layout is still WIP, and some fields are
reserved for the future use by design.

Any comments are welcome.

Subject: staging: erofs: add erofs in-memory stuffs

 - erofs_sb_info:
   contains erofs-specific in-memory information.

 - erofs_vnode:
   contains vfs_inode and other fs-specific information.
   same as super block, the only one in-memory definition exists.

 - erofs_map_blocks
   plays a role in the file L2P mapping

Subject: staging: erofs: introduce xattr & acl support

This implements xattr and acl functionalities.

Inline and shared xattrs are introduced for flexibility.
Specifically, if the same xattr occurs for many times
in a large number of inodes or the value of a xattr is so large
that it isn't suitable to be inlined, a shared xattr
kept in the xattr meta will be used instead.

Subject: staging: erofs: introduce error injection infrastructure

This patch introduces error injection infrastructure, with it, we can
inject error in any kernel exported common functions which erofs used,
so that it can force erofs running into error paths, it turns out that
tests can cover real rare paths more easily to find bugs.

Subject: staging: erofs: <linux/tagptr.h>: introduce tagged pointer

Currently kernel has scattered tagged pointer usages hacked
by hand in plain code, without a unique and portable functionset
to highlight the tagged pointer itself and wrap these hacked code
in order to clean up all over meaningless magic masks.

Therefore, this patch introduces simple generic methods to fold
tags into a pointer integer. It currently supports the last n bits
of the pointer for tags, which can be selected by users.

In addition, it will also be used for the upcoming EROFS filesystem,
which heavily uses tagged pointer approach for high performance
and reducing extra memory allocation.

Subject: staging: erofs: introduce pagevec for unzip subsystem

For each compressed cluster, there is a straight-forward
way of allocating a fixed or variable-sized (for VLE) array
to record the corresponding file pages for its decompression
if we decide to decompress these pages asynchronously (eg.
read-ahead case), however it could take much extra on-heap
memory compared with traditional uncompressed filesystems.

This patch introduces a pagevec solution to reuse some
allocated file page in the time-sharing approach storing
parts of the array itself in order to minimize the extra
memory overhead, thus only a constant and small-sized array
used for booting the whole array itself up will be needed.

From 02827e1796b33f1794966f5c3101f8da2dfa9c1d Mon Sep 17 00:00:00 2001

Subject: staging: erofs: add erofs_map_blocks_iter

This patch introduces an iterable L2P mapping
operation 'erofs_map_blocks_iter'.
Compared with 'erofs_map_blocks', it avoids
a number of redundant 'release and regrab'
processes if they request the same meta page.

Subject: staging: erofs: add erofs_allocpage

This patch introduces an temporary _on-stack_ page
pool to reuse the freed page directly as much as
it can for better performance and release all pages
at a time, it also slightly reduces the possibility of
the potential memory allocation failure.

Subject: staging: erofs: introduce a customized LZ4 decompression

We have to reduce the memory cost as much as possible,
so we don't want to decompress more data beyond
the output buffer size, however "LZ4_decompress_safe_partial"
doesn't guarantee to stop at the arbitary end position,
but stop just after its current LZ4 "sequence" is completed.

Link: https://groups.google.com/forum/#!topic/lz4c/_3kkz5N6n00

Therefore, I hacked the LZ4 decompression logic by hand,
probably NOT the fastest approach, and hope for better
implementation.

Subject: staging: erofs: add a generic z_erofs VLE decompressor

Currently, this patch only simply implements LZ4
decompressor due to its development priority.

In the future, erofs will support more compression
algorithm and format other than LZ4, thus a generic
decompressor interface will be needed.

Subject: staging: erofs: introduce erofs shrinker

This patch adds a dedicated shrinker targeting to free unneeded
memory consumed by a number of erofs in-memory data structures.

Like F2FS and UBIFS, it also adds:
  - sbi->umount_mutex to avoid races on shrinker and put_super
  - sbi->shrinker_run_no to not revisit recently scaned objects

Subject: staging: erofs: introduce workstation for decompression

This patch introduces another concept used by the unzip
subsystem called 'workstation'. It can be seen as a sparse
array that stores pointers pointed to data structures
related to the corresponding physical blocks.

All lookup cases are protected by RCU read lock. Besides,
reference count and spin_lock are also introduced to
manage its lifetime and serialize all update operations.

'workstation' is currently implemented on the in-kernel
radix tree approach for backward compatibility.
With the evolution of linux kernel, it could be migrated
into XArray implementation in the future.

Subject: staging: erofs: introduce VLE decompression support

This patch introduces the basic in-place VLE decompression
implementation for the erofs file system.

Compared with fixed-sized input compression, it implements
what we call 'the variable-length extent compression' which
specifies the same output size for each compression block
to make the full use of IO bandwidth (which means almost
all data from block device can be directly used for decomp-
ression), improve the real (rather than just via data caching,
which costs more memory) random read and keep the relatively
lower compression ratios (it saves more storage space than
fixed-sized input compression which is also configured with
the same input block size), as illustrated below:

        |---  variable-length extent ---|------ VLE ------|---  VLE ---|
         /> clusterofs                  /> clusterofs     /> clusterofs /> clusterofs
   ++---|-------++-----------++---------|-++-----------++-|---------++-|
...||   |       ||           ||         | ||           || |         || | ... original data
   ++---|-------++-----------++---------|-++-----------++-|---------++-|
   ++->cluster<-++->cluster<-++->cluster<-++->cluster<-++->cluster<-++
        size         size         size         size         size
         \                             /                 /            /
          \                      /              /            /
           \               /            /            /
            ++-----------++-----------++-----------++
        ... ||           ||           ||           || ... compressed clusters
            ++-----------++-----------++-----------++
            ++->cluster<-++->cluster<-++->cluster<-++
                 size         size         size

The main point of 'in-place' refers to the decompression mode:
Instead of allocating independent compressed pages and data
structures, it reuses the allocated file cache pages at most
to store its compressed data and the corresponding pagevec in
a time-sharing approach by default, which will be useful for
low memory scenario.

In the end, unlike the other filesystems with (de)compression
support using a relatively large compression block size, which
reads and decompresses >= 128KB at once, and gains a more
good-looking random read (In fact it collects small random reads
into large sequential reads and caches all decompressed data
in memory, but it is unacceptable especially for embedded devices
with limited memory, and it is not the real random read), we
select a universal small-sized 4KB compressed cluster, which is
the smallest page size for most architectures, and all compressed
clusters can be read and decompressed independently, which ensures
random read number for all use cases.

From 105d4ad857dcbf3dc1288f339c5b09dafbc8f923 Mon Sep 17 00:00:00 2001

Subject: staging: erofs: introduce cached decompression

This patch adds an optional choice which can be
enabled by users in order to cache both incomplete
ends of compressed clusters as a complement to
the in-place decompression in order to boost random
read, but it costs more memory than the in-place
decompression only.

+EROFS is still working in progress, thus it is not suitable
+for all productive uses. play at your own risk :)
+
+TODO List:
+ - add the missing error handling code
+   (mainly existed in xattr and decompression submodules);
+
+ - finalize erofs ondisk format design  (which means that
+   minor on-disk revisions could happen later);
+
+ - documentation and detailed technical analysis;
+
+ - general code review and clean up
+   (including confusing variable names and code snippets);
+
+ - support larger compressed clustersizes for selection
+   (currently erofs only works as expected with the page-sized
+    compressed cluster configuration, usually 4KB);
+
+ - support more lossless data compression algorithms
+   in addition to LZ4 algorithms in VLE approach;
+
+ - data deduplication and other useful features.
+
+erofs-mkfs (preview version) binaries for i386 / x86_64 are available at:
+
+   https://github.com/hsiangkao/erofs_mkfs_binary
+
+It is still in progress opening mkfs source code to public,
+in any case an open-source mkfs will be released in the near future.
+
+
+Code, suggestions, etc, are welcome. Please feel free to

Subject: staging: rtl8192e: ieee80211: Convert from ahash to shash

This is an identical change to the wireless/lib80211 of the same name.
In preparing to remove all stack VLA usage from the kernel[1], this
removes the discouraged use of AHASH_REQUEST_ON_STACK in favor of
the smaller SHASH_DESC_ON_STACK by converting from ahash-wrapped-shash
to direct shash. By removing a layer of indirection this both improves
performance and reduces stack usage. The stack allocation will be made
a fixed size in a later patch to the crypto subsystem.

Fix checkpatch.pl warning:

"Use of volatile is usually wrong: see
Documentation/process/volatile-considered-harmful.rs"

reapable is not used to access h/w directly, so volatile is not
necessary.

>From reading the code, the contexts in which the field may be
updated/accessed across threads are protected by the hw->ctlxq.lock
spinlock, where hw is the device struct, so appears thread-safe.

Subject: staging: wlan-ng: correction to comment in hfa384x_usb

The comment for hfa384x_docmd incorrectly states that usercb_data
should be NULL for DOASYNC calls; in fact, it should be NULL for
DOWAIT calls (this is consistent with the other similar functions and
the rest of the comment text).

Subject: staging:rtl8192u: Rename CmdID - Style

Rename the member variable CmdId to cmd_id. This change clears the
checkpatch issue with CamelCase naming. The change is purely a coding
style change which should have no impact on runtime code execution.

Subject: staging:rtl8192u: Remove proxy array rtl819XAGCTAB_Array - Style

Remove the array rtl819XAGCTAB_Array which is only a proxy to the
array Rtl8192UsbAGCTAB_Array. There appears to be no purpose
served by this implementation, other then to obscure the
Rtl8192UsbAGCTAB_Array structure, which is actually written to and
read from.

The array rtl819XRadioA_Array serves as a proxy array for the actual

Subject: staging:rtl8192u: Rename RF90_RADIO_PATH_E - Style

Rename the enumerated type RF90_RADIO_PATH_E to rf90_radio_path_e.
Whilst it is not flagged as an issue by checkpatch, types are meant
to be named in lowercase.

This change is purely a coding style change which should have no
impact on runtime code execution.

Subject: staging:rtl8192u: Remove repeated definitions - Style

Remove bit field masks which are defined in two files: r819xU_phy.h
and r819xU_phyreg.h. Or in the case of bMaskByte3 defined but never used.

The definitions have been removed from the file r819xU_phy.h.

This is a coding style change, which should have no impact on runtime
code execution.

Subject: staging:rtl8192u: Rename eRFPath - Style

Rename the variable eRFPath to e_rfpath. This change resolves a
checkpatch issue with CamelCase naming. The variable name is used both
as a parameter name in function definitions, function prototypes and as
a local variable.

This change is purely a coding style change which should have no impact
on runtime code execution.

Subject: staging:rtl8192u: Remove typedef and rename TX_TS_RECORD - Style

Remove the typdef from structure TX_TS_RECORD and rename to tx_ts_record.
The removal of the typedef clears the checkpatch issue with creating new
types in code. The name change, whilst not specifically flagged by
checkpatch, is an issue since types are meant to be named in lowercase.

These changes are purely coding style changes and should have no impact
on runtime execution.

Subject: staging:rtl8192u: Rename TsCommonInfo - Style

Rename the member variable TsCommonInfo in two structures, both
tx_ts_record and RX_TS_RECORD. This member variable is used in both
structures and in both cases causes a checkpatch issue with CamelCase
naming.

The changes are purely coding style and should not impact runtime
code execution.

Subject: staging:rtl8192u: Rename TxCurSeq - Style

Rename the member variable TxCurSeq to tx_cur_seq. This change clears
the checkpatch issue with CamelCase naming.

The changes are coding style changes which should not impact runtime
code execution.

Subject: staging:rtl8192u: Rename bAddBaReqInProgress - Style

Rename the member variable bAddBaReqInProgress to add_ba_req_in_progress
This change clears the checkpatch issue with CamelCase naming.

Changes are purely coding style and should have no impact on runtime
code execution.

Subject: staging:rtl8192u: Remove typedef and rename RX_TS_RECORD - Style

Remove the typedef from structure RX_TS_RECORD, this change clears the
checkpatch issue with creation of new types.

Additionally the structure is renamed from RX_TS_RECORD to rx_ts_record.
Whilst this is not raised as a checkpatch error structures are meant to
be named in lower case.

These changes are coding style changes which should have no impact on
runtime code execution.

Subject: staging:rtl8192u: Rename RxAdmittedBARecord - Style

Rename the member variable RxAdmittedBARecord to rx_admitted_ba_record.
This change clears the checkpatch issue with CamelCase naming.

The resulting changes are coding style in nature and as such should have
no impact on runtime code execution.

Subject: staging: gasket: page table: simplify comments for static functions

Static functions don't need kernel doc formatting, can be simplified.
Reformat comments that can be single-line.  Remove extraneous text.

From 26fd80ead0fe4dec100d6c2f8ce28897f2e25f2c Mon Sep 17 00:00:00 2001
From: Todd Poynor <toddpoynor@google.com>

Subject: staging: gasket: apex: fix function param line continuation style

Fix multi-line alignment formatting to look like:
      int ret = long_function_name(device, VARIABLE1, VARIABLE2,
                                   VARIABLE3, VARIABLE4);

Many of these TODO items were previously cleaned up during the conversion
to standard logging functions.

Rename the union ACI_AIFSN to aci_aifsn and remove the typedef directive.

The removal of the typedef clears the checkpatch issue with defining

Subject: staging:rtl8192u: Remove unused constants - Style

Remove defined constants from code, since they are never actually
used in code. This is a simple coding style change which should have
no impact on runtime code execution.

Subject: staging:rtl8192u: Remove typedef of struct cmpk_txfb_t - Style

Remove the typedef of the structure cmpk_txfb_t. This clears the
checkpatch issue with defining new types.

Additionally the type is renamed from cmpk_txfb_t to cmd_pkt_tx_feedback
removing the '_t' as the typedef has been removed.

These changes are purely coding style in nature and should have no
impact on runtime code execution.

Subject: staging:rtl8192u: Refactor use of enum dm_dig_sta_e - Style

Refactor the use of the enumerated type dm_dig_sta_e, which is not
actually used for type checking by the compiler.

The typedef of dm_dig_sta_e is removed to clear the checkpatch issue
with defining new types, and the enumerated type is left with the name
enum dynamic_init_gain_state

The enumerated type defines values for the enumeration, which are used
by both dig_state and dig_highpwr_state, (members of the struct dig).
Both of those variables were defined as being of type u8. This negates
any usefulness of the use of the enumeration, (compiler type checking).

To make use of the compiler's type-checking the two member variables,
dig_state and dig_highpwr_state have been changed to being of type
enum dynamic_init_gain_state. The enumerated type has been moved above
the struct dig definition so that the enumeration is already defined
when the compiler reaches the two types using the enumerated type.

These changes, whilst convoluted, are purely coding style in nature and
should not impact runtime code execution.

Subject: staging:rtl8192u: Refactor enum dm_ratr_sta_e usage - Style

The enumerated type dm_ratr_sta_e was defined in the file
drivers/staging/rtl8192u/r8192U_dm.h but never actually used in that
file. The only variable which uses this enumerated type is 'ratr_state',
a member variable of the _rate_adaptive structure defined in the file
drivers/staging/rtl8192u/r8192U.h.

To clarify and place the enumerated type close to where it is used the
type was moved to the drivers/staging/rtl8192u/r8192U.h file.

In addition the member variable 'ratr_state' which uses the enumerated
constants was declared as being of type 'u8'. This negates any advantage
of the enumerated type, compiler type-checking, so that member variable's
type has been changed to being of the enumerated type.

The typedef from the enumerated type has been removed to clear the
checkpatch issue with defining new types. Additionally the name of the
type has been left as enum dynamic_ratr_state

This is a coding style change and should have no impact on runtime code
execution.

Subject: staging:rtl8192u: Remove enum dm_dig_op_e - Style

Remove the enumerated type dm_dig_op_e. The type is only used as a
parameter to the function dm_change_dynamic_initgain_thresh(), but
that function is never referenced in the code at all.

I would consider this to be a coding style change as the function is
never referenced and as a result the enumeration is never used. In
any case there should be no impact on runtime code execution.

Subject: staging:rtl8192u: Refactor enum dm_dig_alg_e - Style

The enumerated type dm_dig_alg_e is only used by one variable in the
code, 'dig_algorithm', a member variable of the structure dig. That
member variable was defined to be of type 'u8' thus negating any
advantage of the use of an enumerated type, (compiler type-checking).

The type of the variable 'dig_algorithm' has been change to reflect
its use of the enumeration and the enumerated type moved in the file
so that it appears before it is used in the file.

Additionally the 'typedef' has been removed to clear the checkpatch
issue with defining new types, and the type renamed to
enum dig_algorithm.

The enumerated constant DIG_ALGO_MAX has been removed from the type
since it is never used in the code.

These changes are all coding style in nature and as such should have
no impact on runtime code execution.

Subject: staging:rtl8192u: Refactor enum dm_dig_cs_ratio_e - Style

The enumerated type dm_dig_cs_ratio_e is never actually used as a type,
but only as a collection of related constants. This is because the
variables, which use the defined constant values, are defined as being
of type u8 rather then tne enumerated type. This omission negates the
possibility of taking advantage of compiler type checking.

To enable the use of compiler type checking of the enumeration the two
variables, (curcs_ratio_state & precs_ratio_state), which use the type's
constants have their types changed from u8 to enum dig_cck_cs_ratio_state.

Additionally the types declaration has been moved above the dig
structure, where the type is used. The 'typedef' keyword has been
removed from the type to clear the checkpatch issue with defining new
types. And the constant DIG_CS_MAX has been removed since this is never
used in the code.

These changes are purely coding style changes and should not impact
on runtime code execution.

Subject: staging:rtl8192u: Refactor enum DM_CCK_Rx_Path_Method - Style

The enumerated type DM_CCK_Rx_Path_Method is used as a container for
constant definitions, rather then an enumerated type enabling compiler
type checking. To correct this, the variable which uses the constants,
defined by the enumeration, has had its type changed from a u8 to the
enumeration.

Additionally the type has been moved above the structure where the type
is used, to avoid compiler error. The typedef has been removed from the
enumerated type to clear the checkpatch issue with defining new types.
The name of the type has been changed to cck_rx_path_method to clear
the checkpatch issue with CamelCase naming. And the enumerated constant
CCK_Rx_Version_MAX has been removed, since it is never used in code.

The changes are all coding style in nature and so should have no
impact on runtime code execution.

There's not been any work on this driver since it was originally merged,
and it really needs to be rewritten to use the serdev layer instead if
people really need/want it.

apex.h is supposed to contain kernel-userspace interface definitions,
but has a number of defines that are only used by apex_driver.c or are
not used at all.  Move driver implementation defines not shared with
userspace to the driver source.  Remove unused defines.

Subject: staging: gasket: core: use bool type for ns_capable result

When gasket core was converted from using capable() to use ns_capable()
instead, the type of the variable holding the result should have been
converted from int to bool.

Subject: Revert "staging: gasket: page table: hold references to device and
 pci_dev"

gasket_free_dev() is called only from driver PCI probe and remove
function. It is guaranteed that that pci_dev structure is not going
anywhere during that time; there is no need to take this additional
reference.

This reverts commit dd9d1502feea3c23d412f289aad79e1d4e86d45d.

This modifies vbox_crtc_do_set_base() to take a new framebuffer to

Subject: staging: vboxvideo: Add page-flip support

Adds crtc page-flip support by passing the new requested framebuffer
to vbox_crtc_do_set_base().

Note there is no attempt to support vblank interrupts, it's not
not known how to do this in VBOX or if it is even possible. Since
this page-flip implementation does not try to sync the page-flip
to vertical blanking, tearing effects are possible.

wilc1000-sdio.ko module. After these changes only wilc1000-spi.ko or
wilc1000-sdio.ko modules are required for SPI and SDIO respectively.
These changes are done to address below TODO item.

Subject: staging: wilc1000: refactor wilc_wlan_handle_isr_ext to avoid goto
 statement

Refactor wilc_wlan_handle_isr_ext() to avoid the use of the goto label.
Also avoid the unnecessary NULL check for 'wilc->rx_buffer' and
calling wilc_wlan_handle_rxq() only after wilc_wlan_rxq_add() call.

Subject: staging: wilc1000: fix endianness warnings reported by sparse

This patch fixes the sparse warnings by making use of le32_to_cpus() &
cpu_to_le32s() conversion API's.
Remove the unnecessary byte-order conversion in
wilc_wlan_parse_response_frame() as the data is copied using individual
byte operation.

Also added the byte-order conversion for 'header' in
wilc_wfi_monitor_rx() & wilc_wfi_p2p_rx() as received in LE byte-order.

The link [1] contains the details of discussion related to this patch.

-Freescale DPAA2 Ethernet driver
-===============================
-
-This file provides documentation for the Freescale DPAA2 Ethernet driver.
-
-
-Contents
-========
-	Supported Platforms
-	Architecture Overview
-	Creating a Network Interface
-	Features & Offloads
-
-
-Supported Platforms
-===================
-This driver provides networking support for Freescale DPAA2 SoCs, e.g.
-LS2080A, LS2088A, LS1088A.
-
-
-Architecture Overview
-=====================
-Unlike regular NICs, in the DPAA2 architecture there is no single hardware block
-representing network interfaces; instead, several separate hardware resources
-concur to provide the networking functionality:
-        - network interfaces
-        - queues, channels
-        - buffer pools
-        - MAC/PHY
-
-All hardware resources are allocated and configured through the Management
-Complex (MC) portals. MC abstracts most of these resources as DPAA2 objects
-and exposes ABIs through which they can be configured and controlled. A few
-hardware resources, like queues, do not have a corresponding MC object and
-are treated as internal resources of other objects.
-
-For a more detailed description of the DPAA2 architecture and its object
-abstractions see:
-	Documentation/networking/dpaa2/overview.rst
-
-Each Linux net device is built on top of a Datapath Network Interface (DPNI)
-object and uses Buffer Pools (DPBPs), I/O Portals (DPIOs) and Concentrators
-(DPCONs).
-
-Configuration interface:

-The DPNIs are network interfaces without a direct one-on-one mapping to PHYs.
-DPBPs represent hardware buffer pools. Packet I/O is performed in the context
-of DPCON objects, using DPIO portals for managing and communicating with the
-hardware resources.

-Datapath I/O (DPIO) portals provide enqueue and dequeue services, data
-availability notifications and buffer pool management. DPIOs are shared between
-all DPAA2 objects (and implicitly all DPAA2 kernel drivers) that work with data
-frames, but must be affine to the CPUs for the purpose of traffic distribution.
-
-Frames are transmitted and received through hardware frame queues, which can be
-grouped in channels for the purpose of hardware scheduling. The Ethernet driver
-enqueues TX frames on egress queues and after transmission is complete a TX
-confirmation frame is sent back to the CPU.
-
-When frames are available on ingress queues, a data availability notification
-is sent to the CPU; notifications are raised per channel, so even if multiple
-queues in the same channel have available frames, only one notification is sent.
-After a channel fires a notification, is must be explicitly rearmed.
-
-Each network interface can have multiple Rx, Tx and confirmation queues affined
-to CPUs, and one channel (DPCON) for each CPU that services at least one queue.
-DPCONs are used to distribute ingress traffic to different CPUs via the cores'
-affine DPIOs.
-
-The role of hardware buffer pools is storage of ingress frame data. Each network
-interface has a privately owned buffer pool which it seeds with kernel allocated
-buffers.
-
-
-DPNIs are decoupled from PHYs; a DPNI can be connected to a PHY through a DPMAC
-object or to another DPNI through an internal link, but the connection is
-managed by MC and completely transparent to the Ethernet driver.

-Creating a Network Interface
-============================
-A net device is created for each DPNI object probed on the MC bus. Each DPNI has
-a number of properties which determine the network interface configuration
-options and associated hardware resources.
-
-DPNI objects (and the other DPAA2 objects needed for a network interface) can be
-added to a container on the MC bus in one of two ways: statically, through a
-Datapath Layout Binary file (DPL) that is parsed by MC at boot time; or created
-dynamically at runtime, via the DPAA2 objects APIs.
-
-
-Features & Offloads
-===================
-Hardware checksum offloading is supported for TCP and UDP over IPv4/6 frames.
-The checksum offloads can be independently configured on RX and TX through
-ethtool.
-
-Hardware offload of unicast and multicast MAC filtering is supported on the
-ingress path and permanently enabled.
-
-Scatter-gather frames are supported on both RX and TX paths. On TX, SG support
-is configurable via ethtool; on RX it is always enabled.
-
-The DPAA2 hardware can process jumbo Ethernet frames of up to 10K bytes.
-
-The Ethernet driver defines a static flow hashing scheme that distributes
-traffic based on a 5-tuple key: src IP, dst IP, IP proto, L4 src port,
-L4 dst port. No user configuration is supported for now.
-
-Hardware specific statistics for the network interface as well as some
-non-standard driver stats can be consulted through ethtool -S option.

+DPAA2 Ethernet driver
+===============================
+
+:Copyright: |copy| 2017-2018 NXP
+
+This file provides documentation for the Freescale DPAA2 Ethernet driver.
+
+Supported Platforms
+===================
+This driver provides networking support for Freescale DPAA2 SoCs, e.g.
+LS2080A, LS2088A, LS1088A.
+
+
+Architecture Overview
+=====================
+Unlike regular NICs, in the DPAA2 architecture there is no single hardware block
+representing network interfaces; instead, several separate hardware resources
+concur to provide the networking functionality:
+
+- network interfaces
+- queues, channels
+- buffer pools
+- MAC/PHY
+
+All hardware resources are allocated and configured through the Management
+Complex (MC) portals. MC abstracts most of these resources as DPAA2 objects
+and exposes ABIs through which they can be configured and controlled. A few
+hardware resources, like queues, do not have a corresponding MC object and
+are treated as internal resources of other objects.
+
+For a more detailed description of the DPAA2 architecture and its object
+abstractions see *Documentation/networking/dpaa2/overview.rst*.
+
+Each Linux net device is built on top of a Datapath Network Interface (DPNI)
+object and uses Buffer Pools (DPBPs), I/O Portals (DPIOs) and Concentrators
+(DPCONs).
+

Subject: staging: rtl8188eu: use is_multicast_ether_addr

Use is_multicast_ether_addr instead of custom IS_MCAST.
The variable for the result of IS_MCAST was only used in the
if conditional. So remove the extra variable and move the call
to is_multicast_ether_addr into the conditional.

Subject: staging: rtl8188eu: use is_broadcast_ether_addr

Use is_broadcast_ether_addr instead of checking each byte of the
address array for 0xff. Shortens the code and improves readability.

As required by is_broadcast_ether_addr, the address array sta_addr
is properly aligned in all uses. Thanks to Joe Perches.

Subject: staging:rtl8192u: Clean cmpk_counttxstatistic() comments - Style

The only useful piece of information in the header comment of this
static function was the name of the function and parameters. That
is not useful information, given that they are in the C Source of
the function declaration, a few lines below the comment. The block
comment has been removed.

This is a coding style change, there should be no impact on runtime
code execution.

Subject: staging:rtl8192u: Remove union from aci_aifsn - Style

The union aci_aifsn is not used as a union, but only as a struct.
The union seems to have been used to ensure that the size of the
structure was only a single byte. That size is set by the bitfield
structure, adding a union with an unused byte adds nothing.

The union has been removed. This is a coding style change and
should not impact runtime code execution.

From 893ce9394b3cba7722f9ce01ecba84f35c0211a6 Mon Sep 17 00:00:00 2001
From: John Whitmore <johnfwhitmore@gmail.com>

Subject: staging:rtl8192u: Remove union from qos_tsinfo - Style

The union is never used as a union but only as a bitfield struct.
One side of the union (u8 charData[3];) Only seems to be present to
ensure that the structures size is 3 bytes in length. That length, of
the structure is dictated by the largest element of the union, so the
byte array only dictates size if it's the largest element of the union.
The byte array and union add nothing.

The union has therefore been removed and the structure and access to
the structure simplified.

Additionally since one of the bitfield variables (ucAccessPolicy)
spans a byte boundary the base type of the bitfield has been changed
from u8 to u16. Compilers have probably moved on from having an issue
with this, call it OCD.

The changes are coding style in nature and should not impact runtime
code execution.

Subject: staging:rtl8192u: Rename members of struct qos_tsinfo - Style

The member variables of struct qos_tsinfo all cause checkpatch issues
with CamelCase naming. As the variables are used in so few places the
changes are combined into this single patch.

Additionally the member variable usReserved is never used in code so
has been removed.

These are all coding style changes which should have no impact on
runtime code execution.

From 9365607ac1c91e8ee4dbda7e1c015f3d2eca489a Mon Sep 17 00:00:00 2001
From: John Whitmore <johnfwhitmore@gmail.com>
Date: Tue, 31 Jul 2018 21:59:56 +0100
Subject: staging:rtl8192u: Refactor union TSPEC_BODY - Style

The union TSPEC_BODY is never used as a union. The union comprises an
array of bytes and a bitfield structure, both of which are 55 bytes in
length, but the byte array is never used. As a result the union has
been truncated to the bitfield struct, which is actually used.

Additionally the typedef has been removed from the structure to clear
the checkpatch issue with defining new types. Additionally the name has
been changed to lowercase to comply with coding style.

These changes are all coding style changes which should have no impact
on runtime code execution.

Subject: staging:rtl8192u: Rename tspec_body members - Style

The member variables of the tspec_body have been renamed to clear the
checkpatch issue with CamelCase naming. As these member variables are
never used in the code the changes are combined into this single
patch.

These changes are coding style changes which should have no impact on
runtime code execution.

A number of structures have been commented out of code. Obviously they
are not used and as a result have been removed from the code.

This is a coding style change which should have no impact on runtime

Rename the structure OCTET_STRING to octet_string. This is to comply

typedef directive is removed to clear the checkpatch issue with
defining new types.

These are coding style changes which should have no impact on runtime

Subject: staging:rtl8192u: Remove unused UP2AC - Style

The macro UP2AC is commented out of the header file so the macro and its
associated comment are removed.

This is a coding style change which should have no impact on runtime
code execution.

The macro IsACValid is renamed to resolve the checkpatch issue with
CamelCase naming. In addition the parameter has parenthesis added to
clear the checkpatch issue with precedence issues.

These changes are coding style changes and as such should have not
impact on runtime code execution.

Subject: staging: gasket: remove "reset type" param from framework

The "type of reset" parameter to the gasket device reset APIs isn't
required by the only gasket device submitted upstream, apex.

The framework documents the param as private to the device driver and a
pass-through at the gasket layer, but the gasket core calls the device
driver with a hardcoded reset type of zero, which is not documented as
having a predefined meaning.

In light of all this, remove the reset type parameter from the
framework.  Remove the reset ioctl reset type parameter, and bump the
framework version number to reflect the interface change.

Subject: staging: gasket: apex: drop reset type param

Apex doesn't implement different types of resets based on the reset type
param passed through the gasket layer or from userspace via the
gasket_reset ioctl.  The reset type is dropped from the gasket framework
in a previous patch due to a lack of present need and non-conforming use
of this parameter by the framework.  Drop the parameter from the apex
driver as well.

Caused by various commits creating erofs in the staging tree interacting
with various commits redoing the mount infrastructure in the vfs tree.

I have disabed CONFIG_EROFS_FS for now:"

The reason of compiling error is:

Since -next collects and merges developing patches including common vfs
stuff from multi-trees, but those patches didn't cover erofs, such as:

('vfs: Suppress MS_* flag defs within the kernel unless explicitly enabled")
https://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git/commit/?h=for-next&id=109b45090d7d3ce2797bb1ef7f70eead5bfe0ff3

("vfs: Require specification of size of mount data for internal mounts")
https://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git/commit/?h=for-next&id=0a191e4505a4f255e6513b49426213da69bf0e80

Above vfs related patches has not been merged in staging tree, if we
submit those erofs patches to staging mailing list and after including
them in staging-{test,nexts} tree, it can easily cause compiling error.

We worked out some patches to adjust those vfs change, but now we just
submit them to -next tree temporarily to avoid compiling error.

For potentail conflict in between erofs and vfs changes in incoming
merge window, Stephen suggested that we can disable CONFIG_EROFS_FS
temporarily to pass merge window, and after that we can do restore by
reenabling CONFIG_EROFS_FS and applying those fixing patches. Also
Greg confirmed this solution.

So, let's disable compiling erofs for a while.

and remove the now unused odm_RegDefine11N.h.

The defines from odm_RegDefine11N.h are defined with the same values
in rtlwifi/phydm/phydm_regdefine11n.h.

There is one define that is named different, but that one is not
used in the rtl8188eu code.

Subject: staging: wilc1000: replace ISWILC1000() macro with inline function

Cleanup patch to avoid below checkpatch issue by replacing the macro
with inline function.

Macro argument 'id' may be better as '(id)' to avoid precedence issues.

Subject: staging:rtl8192u: Remove debug member from structures - Style

Two structures, (struct dig and struct dynamic_rx_path_sel) contain
a u8 member variable representing debug setting. In the file r8192U_dm.c
these member variables, for both structures, are initialised to an
enumerated constant 'DM_DBG_OFF'. The member variables are never
assigned another value, other then off. Later in code the member
variables are tested to for equality to 'DM_DBG_OFF' and if that is the
case an assignment statement is executed.

Since the value of the variables is always off the test is redundant and
the conditional branch can just be executed without the test. Since the
member variables are then actually used both have been removed, along
with the enumerated type which defines debug status, on/off.

These are coding style changes to remove unused or redundant code, there
should be no impact on runtime code execution.

Subject: staging:rtl8192u: Remove member variable rx_gain_range_max - Style

The structure 'dig' defines a member variable, (rx_gain_range_max)
which is initialised to the value 'DM_DIG_MAX', (a defined constant).
The variable is then used to test and set another variable. Since
the member rx_gain_range_max is never assigned any other value then
the constant 'DM_DIG_MAX' the code might as well simply use that
constant, rather the a member variable set to that constant.

The member variable has been removed and the constant used directly
in the code. This is a coding style change which should not impact
runtime code execution.

Subject: staging:rtl8192u: Remove unused extern DM_RxPathSelTable - Style

The file r8192U_dm.h defines the structure DM_RxPathSelTable as being
external. The structure is however declared in r8192U_dm.c and only
used locally in that file.

As a result the external definition has been removed and the declaration
in r8192U_dm.c changed to being of type static.

This is a coding style change which should not impact runtime code
execution.

Subject: staging:rtl8192u: Remove member variable Enable - Style

The structure dynamic_rx_path_sel defines a member variable 'Enable'
which is initialised and later tested. The variable is however never
changed to the test is redundant and the member variable is then never
used.

The member variable, initialisation and test have all been removed.

This is a coding style change which should not impact runtime code
execution.

Subject: staging:rtl8192u: Remove member reserved - Style

The structure dynamic_rx_path_sel contains a u8 member variable called
reserved. This member variable is never actually used in the code.

The naming suggests that the sizeof the structure is significant but
the only use of the structure is a local static in r8192U_dm.c:

static struct dynamic_rx_path_sel DM_RxPathSelTable;

There is no apparent significance to the sizeof the declared structure
DM_RxPathSelTable. As a result the reserved member variable has been
removed from the structure.

This is a coding style change which should have no impact on runtime
code execution.

Subject: staging:rtl8192u: Refactor DCMD_TXCMD_T structure - Style

The structure DCMD_TXCMD_T is declared with a typedef, which causes a
checkpatch issue with defining new types. As a result the typedef has
been removed.

The structure's name DCMD_TXCMD_T, as a type, is meant to be lowercase
so has been renamed to tx_config_cmd.

The structures three members, (Op, Length, and Value) are all violating
the coding standard policy on CamelCase naming, so have all been renamed.
They have been renamed with longer names, (cmd_op, cmd_length and
cmd_value), to make the variable names easier to search for in code.

The magic numbers '4' and '12' have both been replaced with sizeof()
calls, as they both represent the size of data elements.

These are coding style changes which should have no impact on runtime
code execution.

Subject: staging:rtl8192u: Rename DM_DIG_MIN_Netcore - Style

The constant DM_DIG_MIN_Netcore causes a checkpatch issue with CamelCase
naming so has been renamed to DM_DIG_MIN_NETCORE.

This is a simple coding style change which should have no impact on
runtime code execution.

Subject: staging:rtl8192u: Clean up of spacing - Style

Multiple blank line, which cause an issue with checkpath, have been
removed and the spacing of definitions have been aligned to look
cleaner.

These are coding style changes which should have no impact on
runtime code execution.

Subject: staging:rtl8192u: Remove typedef and rename QOS_TCLAS - Style

Remove the typedef from the union QOS_TCLAS, which causes a checkpatch
issue with defining new types. In addition, as a type, the name should
be in lowercase so has been changed.

These are coding style changes and should have no impact on runtime
code execution.

Subject: staging:rtl8192u: Rename types in QOS_TCLAS union - Style

Whilst none of the structures inside the qos_tclas union are used, their
names conflict with the coding standard being named in uppercase.
The names of all five have been changed to lowercase.

This is a style change, and since none of the structures are referenced,
these changes should have no impact on runtime code execution.

Subject: staging:rtl8192u: Rename multiple variables - Style

All of the variables used within the structures of the union qos_tclas
cause checkpatch issue due to CamelCase naming. As none the member
variables are used in code all have been changed on one patch.

These changes are coding style in nature and should not impact runtime
code execution.

Subject: staging:rtl8192u: Remove comments - Style

Removal of three comments. The comments in question do not add anything
to the understanding of the code, and if they are necessary it would
imply that the structure and its member variables are badly named.

This is a simple style change and should have no impact on runtime
code execution.

Subject: staging: gasket: core: move core PCI calls to device drivers

Remove gasket wrapping of PCI probe, enable, disable, and remove
functions.  Replace with calls to add and remove PCI gasket devices,
to be called by the gasket device drivers.

Subject: staging: gasket: core: remove device enable and disable callbacks

Device enable/disable operations are moving from being initiated through
the gasket framework to being initiated by the gasket device driver.
The driver can perform any processing needed for these operations before
or after the calls into the framework.  Neither of these callbacks are
implemented for the only gasket driver upstream today, apex.

Subject: staging: gasket: core: let device driver enable/disable gasket device

Move gasket device enable/disable functions from internal calls to
external calls from the gasket device drivers.  The device driver will
call these functions at appropriate times in its processing, placing
the device driver in control of this sequence and reducing the need for
callbacks from framework back to the device drivers during the
enable/disable sequences.

From 8571c62d45cb7e9fdff87fe5132002d17fbce7a3 Mon Sep 17 00:00:00 2001
From: Sergio Paracuellos <sergio.paracuellos@gmail.com>
Date: Fri, 3 Aug 2018 10:26:54 +0200
Subject: staging: mt7621-pci: use generic kernel pci subsystem read and write

map_bus callback is called before every .read/.write operation.
Implement it and change custom read write operations for the
pci subsystem generics. Make the probe function to don't use
legacy stuff and request bus resources directly. Get pci register
base and ranges from device tree.
The driver is not using PCI_LEGACY code anymore and shall use the
PCI_DRIVERS_GENERIC option to correct compile it. Add also new
Kconfig file for this controller setting there its correct dependencies.

Subject: staging: mt7621-pci: remove dead code derived to not use custom reads
 and writes

Driver is using now pci subsystem generics reads and writes and requesting
bus resources without using legacy code functions. Because of this there is
a lot of dead code that can be removed.

Subject: staging: mt7621-pci: avoid register duplication per controller using
 pcie_[read|write]

Use pcie_[read|write] fucntions to read and write controller registers.
Define those only by offset and pass controller offset + register offset
relative to base address to functions.

RALINK_PCI_PCICFG_ADDR and RALINK_PCI_PCIMSK_ADDR are defined to be directly
referenced for read and write. Use pcie_read and pcie_write instead changing
its definition to a simple relative offset to pcie base address.

Subject: staging: mt7621-pci: remove RALINK_PCI_BASE from remaining
 definitions

RALINK_PCI_BASE has no sense and this driver has base address readed
and mapped from device tree. Remove remaining uses of it and
change code to use pcie_read and pcie_write functions in places
where this was being used.

Subject: staging: comedi: ni_mio_common: fix subdevice flags for PFI subdevice

The PFI subdevice flags indicate that the subdevice is readable and
writeable, but that is only true for the supported "M-series" boards,
not the older "E-series" boards.  Only set the SDF_READABLE and
SDF_WRITABLE subdevice flags for the M-series boards.  These two flags
are mainly for informational purposes.

Use is_multicast_ether_addr instead of custom IS_MCAST in

There is only one use, so remove the extra variable for the
result of IS_MCAST.

Subject: staging: rtl8188eu: remove unused array dB_Invert_Table
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Array dB_Invert_Table is declared but not used, hence it is redundant
and can be removed.

Cleans up clang warning:
warning: ‘dB_Invert_Table’ defined but not used [-Wunused-const-variable=]

Subject: staging:rtl8192u: Add spaces around '+' operator - Style

Add spaces around '+' operator as required by the coding standard.
This clears the checkpatch issue.

This change is purely coding style in nature and should have not
effect on runtime code execution.

Subject: staging:rtl8192u: Remove unused macro definitions - Style

Removed unused macro definitions as they add nothing to the code.

This is a coding style change which should have no impact on runtime
code execution.
