Stop reporting SW_DOCK events because this breaks suspend-on-lid-close.
SW_DOCK should only be reported for docking stations, but all the DSDTs in
my DSDT collection which use the intel-vbtn code, always seem to use this
for 2-in-1s / convertibles and set SW_DOCK=1 when in laptop-mode (in tandem
with setting SW_TABLET_MODE=0).
This causes userspace to think the laptop is docked to a port-replicator
and to disable suspend-on-lid-close, which is undesirable.
Map the dock events to KEY_IGNORE to avoid this broken SW_DOCK reporting.
Note this may theoretically cause us to stop reporting SW_DOCK on some
device where the 0xCA and 0xCB intel-vbtn events are actually used for
reporting docking to a classic docking-station / port-replicator but
I'm not aware of any such devices.
Also the most important thing is that we only report SW_DOCK when it
reliably reports being docked to a classic docking-station without any
false positives, which clearly is not the case here. If there is a
chance of reporting false positives then it is better to not report
SW_DOCK at all.

Cleanup create_attributes_level_sysfs_files():
1. There is no need to call sysfs_remove_file() on error, sysman_init()
will already call release_attributes_data() on failure which already does
this.
2. There is no need for the pr_debug() calls sysfs_create_file() should
never fail and if it does it will already complain about the problem
itself.

Cleanup sysman_init() error-exit handling:
1. There is no need for the fail_reset_bios and fail_authentication_kset
eror-exit cases, these can be handled by release_attributes_data()
2. Rename all the labels from fail_what_failed, to err_what_to_cleanup
this is the usual way to name these and avoids the need to rename
them when extra steps are added.

All calls of init_bios_attributes() will result in a
goto fail_create_group if they fail, which calls
release_attributes_data().
So there is no need to call release_attributes_data() from
init_bios_attributes() on failure itself.

During some of the error-exit paths it is possible that
release_attributes_data() will get called multiple times,
which results in exit_foo_attributes() getting called multiple
times.
Make it safe to call exit_foo_attributes() multiple times,
avoiding double-free()s in this case.
Note that release_attributes_data() really should only be called
once during error-exit paths. This will be fixed in a separate patch
and it is good to have the exit_foo_attributes() functions modified
this way regardless.

On some system the WMI GUIDs used by dell-wmi-sysman are present but there
are no enum type attributes, this causes init_bios_attributes() to return
-ENODEV, after which sysman_init() does a "goto fail_create_group" and then
calls release_attributes_data().
release_attributes_data() calls kset_unregister(wmi_priv.main_dir_kset);
but before this commit it was missing a "wmi_priv.main_dir_kset = NULL;"
statement; and after calling release_attributes_data() the sysman_init()
error handling does this:
if (wmi_priv.main_dir_kset) {
kset_unregister(wmi_priv.main_dir_kset);
wmi_priv.main_dir_kset = NULL;
}
Which causes a second kset_unregister(wmi_priv.main_dir_kset), leading to
a double-free, which causes a crash.
Add the missing "wmi_priv.main_dir_kset = NULL;" statement to
release_attributes_data() to fix this double-free crash.

Testing has shown that setting /sys/firmware/acpi/platform_profile to
"balanced" when /sys/bus/platform/devices/thinkpad_acpi/dytc_lapmode
reports 1, causes dytc_lapmode to get reset to 0 and then it becomes
stuck at 0 for aprox. 30 minutes even if the laptop is used on a lap.
Disabling CQL (when enabled) before issuing the DYTC_CMD_RESET to get
back to balanced mode and re-enabling it afterwards again, like the
code already does when switching to low-power / performance mode fixes
this.

On many recent ThinkPad laptops, there's a new LED next to the ESC key,
that indicates the FnLock status.
When the Fn+ESC combo is pressed, FnLock is toggled, which causes the
Media Key functionality to change, making it so that the media keys
either perform their media key function, or function as an F-key by
default. The Fn key can be used the access the alternate function at any
time.
With the current linux kernel, the LED doens't change state if you press
the Fn+ESC key combo. However, the media key functionality *does*
change. This is annoying, since the LED will stay on if it was on during
bootup, and it makes it hard to keep track what the current state of the
FnLock is.
This patch calls an ACPI function, that gets the current media key
state, when the Fn+ESC key combo is pressed. Through testing it was
discovered that this function causes the LED to update correctly to
reflect the current state when this function is called.
The relevant ACPI calls are the following:
\_SB_.PCI0.LPC0.EC0_.HKEY.GMKS: Get media key state, returns 0x603 if the FnLock mode is enabled, and 0x602 if it's disabled.
\_SB_.PCI0.LPC0.EC0_.HKEY.SMKS: Set media key state, sending a 1 will enable FnLock mode, and a 0 will disable it.

According to datasheets, chips like mXT1386 have a WAKE line, it is used
to wake the chip up from deep sleep mode before communicating with it via
the I2C-compatible interface.
If the WAKE line is connected to a GPIO line, the line must be asserted
25 ms before the host attempts to communicate with the controller. If the
WAKE line is connected to the SCL pin, the controller will send a NACK on
the first attempt to address it, the host must then retry 25 ms later.
Implement the wake-up methods in the driver. Touchscreen now works
properly on devices like Acer A500 tablet, fixing problems like this:
atmel_mxt_ts 0-004c: __mxt_read_reg: i2c transfer failed (-121)
atmel_mxt_ts 0-004c: mxt_bootloader_read: i2c recv failed (-121)

This reverts commit e9bf96943b408e6c99dd13fb01cb907335787c61.
The topic of the reverted patch is the support for switches with global
VLAN filtering, added by commit 061f6a505ac3 ("net: dsa: Add
ndo_vlan_rx_{add, kill}_vid implementation"). Be there a switch with 4
ports swp0 -> swp3, and the following setup:
ip link add br0 type bridge vlan_filtering 1
ip link set swp0 master br0
ip link set swp1 master br0
What would happen with VLAN-tagged traffic received on standalone ports
swp2 and swp3? Well, it would get dropped, were it not for the
.ndo_vlan_rx_add_vid and .ndo_vlan_rx_kill_vid implementations (called
from vlan_vid_add and vlan_vid_del respectively). Basically, for DSA
switches where VLAN filtering is a global attribute, we enforce the
standalone ports to have 'rx-vlan-filter: off [fixed]' in their ethtool
features, which lets the user know that all VLAN-tagged packets that are
not explicitly added in the RX filtering list are dropped.
As for the sja1105 driver, at the time of the reverted patch, it was
operating in a pretty handicapped mode when it had ports under a bridge
with vlan_filtering=1. Specifically, it was unable to terminate traffic
through the CPU port (for further explanation see "Traffic support" in
Documentation/networking/dsa/sja1105.rst).
However, since then, the sja1105 driver has made considerable progress,
and that limitation is no longer as severe now. Specifically, since
commit 2cafa72e516f ("net: dsa: sja1105: add a new
best_effort_vlan_filtering devlink parameter"), the driver is able to
perform CPU termination even when some ports are under bridges with
vlan_filtering=1. Then, since commit 8841f6e63f2c ("net: dsa: sja1105:
make devlink property best_effort_vlan_filtering true by default"), this
even became the default operating mode.
So we can now take advantage of the logic in the DSA core.

====================
pull-request: can 2021-03-20
this is a pull request of 2 patches for net/master.
The first patch is by Oliver Hartkopp. He fixes the TX-path in the
ISO-TP protocol by properly initializing the outgoing CAN frames.
The second patch is by me and reverts a patch from my previous pull
request which added MODULE_SUPPORTED_DEVICE to the peak_usb driver. In
the mean time in Linus's tree the entirely MODULE_SUPPORTED_DEVICE was
removed. So this reverts the adding of the new MODULE_SUPPORTED_DEVICE
to avoid the merge conflict.
If you prefer to resolve the merge conflict by hand, I'll send a new
pull request without that patch.

We only program the sequencer type for TX endpoints. So move the
definition of the sequencer type fields into the TX-specific portion
of the endpoint configuration data. There's no need to maintain
this in the IPA structure; we can extract it from the configuration
data it points to in the one spot it's needed.
We previously specified the sequencer type for RX endpoints with
INVALID values. These are no longer needed, so get rid of them.

An IPA endpoint has a sequencer that must be configured based on how
the endpoint is to be used. Currently the IPA code programs the
sequencer type by splitting a value into four 4-bit nibbles. Doing
that doesn't really add much value, and regardless, a better way of
splitting the sequencer type is into two halves--the lower byte
describing how normal packet processing is handled, and the next
byte describing information about processing replicas.
So split the sequencer type into two sub-parts: the sequencer type
and the replication sequencer type. Define the values supported for
the "main" sequencer type, and define the values supported for the
replication part separately.
In addition, the sequencer type names are quite verbose, encoding
what the type includes, but also what it *excludes*. Rename the
sequencer types in a way that mainly describes the number of passes
that a packet takes through the IPA processing pipeline, and how
many of those passes end by supplying the processed packet to the
microprocessor.
The result expands the supported types beyond what is required for
now, but simplifies the way these are defined.

Starting with IPA v4.0, a limit is placed on the number of bytes
outstanding in a transaction, to reduce latency. The limit is
imposed only if this value is non-zero.
We don't use a non-zero value for SC7180, but newer versions of IPA
do. Prepare for that by allowing a programmed value to be specified
in the platform configuration data.

Use the QSB configuration data in ipa_hardware_config_qsb(), rather
than determining in code what values to use based on IPA version.
Pass configuration data to ipa_hardware_config() so it can be passed
to ipa_hardware_config_qsb().

We use ipa_cmd_header_valid() to ensure certain values we will
program into hardware are within range, well in advance of when we
actually program them. This way we avoid having to check for errors
when we actually program the hardware.
Unfortunately the dev_err() call for a bad offset value does not
supply the arguments to match the format specifiers properly.
Fix this.
There was also supposed to be a check to ensure the size to be
programmed fits in the field that holds it. Add this missing check.
Rearrange the way we ensure the header table fits in overall IPA
memory range.
Finally, update ipa_cmd_table_valid() so the format of messages
printed for errors matches what's done in ipa_cmd_header_valid().

In commit 6417f03132a6 ("module: remove never implemented
MODULE_SUPPORTED_DEVICE") the MODULE_SUPPORTED_DEVICE macro was
removed from the kerne entirely. Shortly before this patch was applied
mainline the commit 59ec7b89ed3e ("can: peak_usb: add forgotten
supported devices") was added to net/master. As this would result in a
merge conflict, let's revert this patch.

As stated in f54ec58fee83 ("wimax: move out to staging"), the wimax code
is dead with no known users. It has stayed in staging for 5 months,
with no one willing to take up the codebase for maintance and support,
so let's just remove it entirely for now.
If someone comes along and wants to revive it, a simple revert of this
patch is a good place to start.
