commit d85862ccca452eeb19329e9f4f9a6ce1d1e53561 upstream.
Some older Clevo barebones have problems like no or laggy keyboard after
resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE
quirk.
We could not activly retest these devices because we no longer have them in
our archive, but based on the other old Clevo barebones we tested where the
new quirk had the same or a better behaviour I think it would be good to
apply it on these too.

commit 95a54a96f657fd069d2a9922b6c2d293a72a001f upstream.
TECNO Pocket Go is a kickstarter handheld by manufacturer TECNO Mobile.
It poses a unique feature: it does not have a display. Instead, the
handheld is essentially a pc in a controller. As customary, it has an
xpad endpoint, a keyboard endpoint, and a vendor endpoint for its
vendor software.

commit a2add513311b48cc924a699a8174db2c61ed5e8a upstream.
Some register groups reserve a byte at the end of their continuous
address space. Depending on the variant of silicon, this field may
share the same memory space as the lower byte of the system status
register (0x10).
In these cases, caching the reserved byte and writing it later may
effectively reset the device depending on what happened in between
the read and write operations.
Solve this problem by avoiding any access to this last byte within
offending register groups. This method replaces a workaround which
attempted to write the reserved byte with up-to-date contents, but
left a small window in which updates by the device could have been
clobbered.
Now that the driver does not touch these reserved bytes, the order
in which the device's registers are written no longer matters, and
they can be written in their natural order. The new method is also
much more generic, and can be more easily extended to new variants
of silicon with different register maps.
As part of this change, the register read and write functions must
be gently updated to support byte access instead of word access.

[ Upstream commit 08bd5b7c9a2401faabdaa1472d45c7de0755fd7e ]
When enabling a pass-through port an interrupt might come before psmouse
driver binds to the pass-through port. However synaptics sub-driver
tries to access psmouse instance presumably associated with the
pass-through port to figure out if only 1 byte of response or entire
protocol packet needs to be forwarded to the pass-through port and may
crash if psmouse instance has not been attached to the port yet.
Fix the crash by introducing open() and close() methods for the port and
check if the port is open before trying to access psmouse instance.
Because psmouse calls serio_open() only after attaching psmouse instance
to serio port instance this prevents the potential crash.

commit 66372fa9936088bf29c4f47907efeff03c51a2c8 upstream.
8BitDo Pro 2 Wired Controller shares the same USB identifier
(2dc8:3106) as a different device, so amend name to reflect that and
reduce confusion as the user might think the controller was misdetected.
Because Pro 2 Wired will not work in XTYPE_XBOXONE mode (button presses
won't register), tagging it as XTYPE_XBOX360 remains appropriate.

commit 907bc9268a5a9f823ffa751957a5c1dd59f83f42 upstream.
Microsoft defined Meta+Shift+F23 as the Copilot shortcut instead of a
dedicated keycode, and multiple vendors have their keyboards emit this
sequence in response to users pressing a dedicated "Copilot" key.
Unfortunately the default keymap table in atkbd does not map scancode
0x6e (F23) and so the key combination does not work even if userspace
is ready to handle it.
Because this behavior is common between multiple vendors and the
scancode is currently unused map 0x6e to keycode 193 (KEY_F23) so that
key sequence is generated properly.
MS documentation for the scan code:
https://learn.microsoft.com/en-us/windows/win32/inputdev/about-keyboard-input#scan-codes
Confirmed on Lenovo, HP and Dell machines by Canonical.
Tested on Lenovo T14s G6 AMD.

[ Upstream commit bffdf9d7e51a7be8eeaac2ccf9e54a5fde01ff65 ]
The driver neglects to free the instance of I2C regmap constructed at
the beginning of the edt_ft5x06_ts_probe() method when probe fails.
Additionally edt_ft5x06_ts_remove() is freeing the regmap too early,
before the rest of the device resources that are managed by devm are
released.
Fix this by installing a custom devm action that will ensure that the
regmap is released at the right time during normal teardown as well as
in case of probe failure.
Note that devm_regmap_init_i2c() could not be used because the driver
may replace the original regmap with a regmap specific for M06 devices
in the middle of the probe, and using devm_regmap_init_i2c() would
result in releasing the M06 regmap too early.

commit fbf8d71742557abaf558d8efb96742d442720cc2 upstream.
Calling irq_domain_remove() will lead to freeing the IRQ domain
prematurely. The domain is still referenced and will be attempted to get
used via rmi_free_function_list() -> rmi_unregister_function() ->
irq_dispose_mapping() -> irq_get_irq_data()'s ->domain pointer.
With PaX's MEMORY_SANITIZE this will lead to an access fault when
attempting to dereference embedded pointers, as in Torsten's report that
was faulting on the 'domain->ops->unmap' test.
Fix this by releasing the IRQ domain only after all related IRQs have
been deactivated.
