Drop the special defines in a bunch of drivers where the

The previous split budget between TX and RX made it return not using
the entire budget but at the same time not having calling called
napi_complete. This sometimes led to the poll to not be called, and at
the same time having TX and RX interrupts disabled resulting in the
driver getting stuck.

Use the device of the device tree node should be rather than the
device of the struct net_device when allocating DMA buffers.
The driver got away with it on sparc32 until commit 53b7670e5735
("sparc: factor the dma coherent mapping into helper") after which the
driver oopses.

There are deadlocks caused by del_timer_sync(&priv->hang_timer) and
del_timer_sync(&priv->rr_timer) in grcan_close(), one of the deadlocks
are shown below:
(Thread 1) | (Thread 2)
| grcan_reset_timer()
grcan_close() | mod_timer()
spin_lock_irqsave() //(1) | (wait a time)
... | grcan_initiate_running_reset()
del_timer_sync() | spin_lock_irqsave() //(2)
(wait timer to stop) | ...
We hold priv->lock in position (1) of thread 1 and use
del_timer_sync() to wait timer to stop, but timer handler also need
priv->lock in position (2) of thread 2. As a result, grcan_close()
will block forever.
This patch extracts del_timer_sync() from the protection of
spin_lock_irqsave(), which could let timer handler to obtain the
needed lock.

Currently, component_match callback functions used in mei refers to the
driver name, assuming that the component device being matched has a
driver bound. It can cause a NULL pointer dereference when a device
without a driver bound registers a component. This is due to the nature
of the component framework where all registered components are matched
in any component_match callback functions. So even if a component is
registered by a totally irrelevant device, that component is also
shared to these callbacks for i915 driver.
To prevent totally irrelevant device being matched for i915 and causing
a NULL pointer dereference for checking driver name, add a NULL check on
dev->driver to check if there is a driver bound before checking the
driver name.
In the future, the string compare on the driver name, "i915" may need to
be refactored too.

The DRM_DP_AUX_CHARDEV and DRM_DP_CEC Kconfig symbols enable code that use
DP helper functions, that are only present if CONFIG_DRM_DISPLAY_DP_HELPER
is also enabled.
But these don't select the DRM_DISPLAY_DP_HELPER symbol, meaning that it
is possible to enable any of them without CONFIG_DRM_DISPLAY_DP_HELPER.
That will lead to the following linking errors with the mentioned config:

Besides making these symbols to select CONFIG_DRM_DISPLAY_DP_HELPER, make
them to depend on DRM_DISPLAY_HELPER, since can't be enabled without it.
Note: It seems this has been an issue for a long time but was made easier
to reproduce after the commit 1e0f66420b13 ("drm/display: Introduce a DRM

Allow OMAP_GPMC to be built as a module.
When building this driver as a module, the symbol
'of_default_bus_match_table' will not be found as it is not being
exported.
The of_match_node() call is redundant anyways as
of_platform_default_populate() already takes care of matching with
'of_default_bus_match_table'. So get rid of that call. This will also
resolve the module build failure.
Move compatible match table to the end where it is usually expected.

So far for armv7 TI platforms, GPMC was being selected by
arch/arm/mach-* architecture Kconfig files.
For K3 platforms, GPMC is no longer required for basic boot and cannot
be always enabled by default by mach- Kconfig.
We need a way for user (or board defconfig) to enable it if required so
make OMAP_GPMC Kconfig option always visible.
Drop COMPILE_TEST as build fails if IRQ_DOMAIN is not enabled.

__add_memory_block() calls both put_device() and device_unregister() when
storing the memory block into the xarray. This is incorrect because
xarray doesn't take an additional reference and device_unregister()
already calls put_device().
Triggering the issue looks really unlikely and its only effect should be
to log a spurious warning about a ref counted issue.

Double free crash is observed when FW recovery(caused by wmi
timeout/crash) is followed by immediate suspend event. The FW recovery
is triggered by ath10k_core_restart() which calls driver clean up via
ath10k_halt(). When the suspend event occurs between the FW recovery,
the restart worker thread is put into frozen state until suspend completes.
The suspend event triggers ath10k_stop() which again triggers ath10k_halt()
The double invocation of ath10k_halt() causes ath10k_htt_rx_free() to be
called twice(Note: ath10k_htt_rx_alloc was not called by restart worker
thread because of its frozen state), causing the crash.
To fix this, during the suspend flow, skip call to ath10k_halt() in
ath10k_stop() when the current driver state is ATH10K_STATE_RESTARTING.
Also, for driver state ATH10K_STATE_RESTARTING, call
ath10k_wait_for_suspend() in ath10k_stop(). This is because call to
ath10k_wait_for_suspend() is skipped later in
[ath10k_halt() > ath10k_core_stop()] for the driver state
ATH10K_STATE_RESTARTING.
The frozen restart worker thread will be cancelled during resume when the
device comes out of suspend.

(cherry picked from commit 1f682dc9fb3790aa7ec27d3d122ff32b1eda1365 in wireless-next)
Currently ath11k will wait 11d scan complete while add interface in
ath11k_mac_op_add_interface(), when system resume without enable
wowlan, ath11k_mac_op_add_interface() is called for each resume, thus
it increase the resume time of system. And ath11k_mac_op_hw_scan()
after ath11k_mac_op_add_interface() also needs some time cost because
the previous 11d scan need more than 5 seconds when 6 GHz is enabled,
then the scan started event will indicated to ath11k after the 11d
scan completed.
While 11d scan/hw scan is running in firmware, if ath11k update channel
list to firmware by WMI_SCAN_CHAN_LIST_CMDID, then firmware will cancel
the current scan which is running, it lead the scan failed. The patch
commit 9dcf6808b253 ("ath11k: add 11d scan offload support") used
finish_11d_scan/finish_11d_ch_list/pending_11d to synchronize the 11d
scan/hw scan/channel list between ath11k/firmware/mac80211 and to avoid
the scan fail.
Add wait operation before ath11k update channel list, function
ath11k_reg_update_chan_list() will wait until the current 11d scan/hw
scan completed. And remove the wait operation of start 11d scan and
waiting channel list complete in hw scan. After these changes, resume
time cost reduce about 5 seconds and also hw scan time cost reduced
obviously, and scan failed not seen.
The 11d scan is sent to firmware only one time for each interface added
in mac.c, and it is moved after the 1st hw scan because 11d scan will
cost some time and thus leads the AP scan result update to UI delay.
Currently priority of ath11k's hw scan is WMI_SCAN_PRIORITY_LOW, and
priority of 11d scan in firmware is WMI_SCAN_PRIORITY_MEDIUM, then the
11d scan which sent after hw scan will cancel the hw scan in firmware,
so change the priority to WMI_SCAN_PRIORITY_MEDIUM for the hw scan which
is in front of the 11d scan, thus it will not happen scan cancel in
firmware.

https://patchwork.ozlabs.org/project/uboot/patch/20220415111049.2565744-1-gaurav.jain@nxp.com/
As explained in the U-Boot patch:
"RNG self tests are run to determine the correct entropy delay.
Such tests are executed with different voltages and temperatures to identify
the worst case value for the entropy delay. For i.MX6SX, it was determined
that after adding a margin value of 1000 the minimum entropy delay should be
at least 12000."

There are 2 common cases when INIT_EX data file might not be
opened successfully and fail the sev initialization:
1. In user namespaces, normal user tasks (e.g. VMM) can change their
current->fs->root to point to arbitrary directories. While
init_ex_path is provided as a module param related to root file
system. Solution: use the root directory of init_task to avoid
accessing the wrong file.
2. Normal user tasks (e.g. VMM) don't have the privilege to access
the INIT_EX data file. Solution: open the file as root and
restore permissions immediately.

The mv88e6xxx driver expects switches that are configured in single chip
addressing mode to have the MDIO address configured as 0. This is due to
the switch ADDR pins representing the single chip addressing mode as 0.
However depending on the device (e.g. MV88E6*41) the switch does not
respond on address 0 or any other address below 16 (the first port
address) in single chip addressing mode. This allows for other devices
to be on the same shared MDIO bus despite the switch being in single
chip addressing mode.
When using a switch that works this way it is not possible to configure
switch driver as single chip addressing via device tree, along with
another MDIO device on the same bus with address 0, as both devices
would have the same address of 0 resulting in mdiobus_register_device
-EBUSY errors for one of the devices with address 0.
In order to support this configuration the switch node can have its MDIO
address configured as 16 (the first address that the device responds
to). During initialization the driver will treat this address similar to
how address 0 is, however because this address is also a valid
multi-chip address (in certain switch models, but not all) the driver
will configure the SMI in single chip addressing mode and attempt to
detect the switch model. If the device is configured in single chip
addressing mode this will succeed and the initialization process can
continue. If it fails to detect a valid model this is because the switch
model register is not a valid register when in multi-chip mode, it will
then fall back to the existing SMI initialization process using the MDIO
address as the multi-chip mode address.
This detection method is safe if the device is in either mode because
the single chip addressing mode read is a direct SMI/MDIO read operation
and has no side effects compared to the SMI writes required for the
multi-chip addressing mode.
In order to implement this change, the reset gpio configuration is moved
to occur before any SMI initialization. This ensures that the device has
the same/correct reset gpio state for both mv88e6xxx_smi_init calls.

phy_attach_direct() first calls phy_init_hw() (which restores interrupt
settings through ->config_intr()), then calls phy_disable_interrupts().
So if phydev->interrupts was previously set to 1, interrupts are briefly
enabled, then disabled, which seems nonsensical.
If it was previously set to 0, interrupts are disabled twice, which is
equally nonsensical.
Deduplicate interrupt disablement.

It is not clear why the original implementation of overwrite support
required the dimm driver to be active before overwrite could proceed. In
fact that can lead to cases where the kernel retains an invalid cached
copy of the labels from before the overwrite. Unfortunately the kernel
has not only allowed that case, but enforced it.
Going forward, allow for overwrite to happen while the label area is
offline, and follow-on with updates to 'ndctl sanitize-dimm --overwrite'
to trigger the label area invalidation by default.
