[ Upstream commit 87a2f10395c82c2b4687bb8611a6c5663a12f9e7 ]

Adds driver support for the USB-C model of Apple's Magic Trackpad 2.

The 2024 USB-C model is compatible with the existing Magic Trackpad 2
driver but has a different hardware ID.

[ Upstream commit 645c224ac5f6e0013931c342ea707b398d24d410 ]

We already have the possibility to force not binding to hid-generic and
rely on a dedicated driver, but we couldn't do the other way around.

This is useful for BPF programs where we are fixing the report descriptor
and the events, but want to avoid a specialized driver to come after BPF
which would unwind everything that is done there.

commit 59548215b76be98cf3422eea9a67d6ea578aca3d upstream.

Due to incorrect dev-&gt;product reporting by certain devices, null
pointer dereferences occur when dev-&gt;product is empty, leading to
potential system crashes.

This issue was found on EXCELSIOR DL37-D05 device with
Loongson-LS3A6000-7A2000-DL37 motherboard.

commit 34851431ceca1bf457d85895bd38a4e7967e2055 upstream.

commit 7d6f065de37c ("HID: i2c-hid: Use address probe to wake on resume")
replaced the retry of power commands with the dummy read "bus probe" we
use on boot which accounts for a necessary delay before retry.

This made at least one Weida device (2575:0910 in an ASUS Vivobook S14)
very unhappy, as the bus probe despite being successful somehow lead to
the following power command failing so hard that the device never lets
go of the bus. This means that even retries of the power command would
fail on a timeout as the bus remains busy.

Remove the bus probe on resume and instead reintroduce retry of the
power command for wake-up purposes while respecting the newly
established wake-up retry timings.

commit 49a397ad24ee5e2c53a59dada2780d7e71bd3f77 upstream.

The tilt data contained in the Bluetooth packets of an Intuos Pro are
supposed to be interpreted as signed values. Simply casting the values
to type `char` is not guaranteed to work since it is implementation-
defined whether it is signed or unsigned. At least one user has noticed
the data being reported incorrectly on their system. To ensure that the
data is interpreted properly, we specifically cast to `signed char`
instead.

And the issue seems to be that the corresponding devres group is not
allocated. Normally, devres_open_group() is called from
__hid_device_probe() but Hyper-V HID driver overrides 'hid_dev-&gt;driver'
with 'mousevsc_hid_driver' stub and basically re-implements
__hid_device_probe() by calling hid_parse() and hid_hw_start() but not
devres_open_group(). hid_device_probe() does not call __hid_device_probe()
for it. Later, when the driver is removed, hid_device_remove() calls
devres_release_group() as it doesn't check whether hdev-&gt;driver was
initially overridden or not.

The issue seems to be related to the commit 62c68e7cee33 ("HID: ensure
timely release of driver-allocated resources") but the commit itself seems
to be correct.

Fix the issue by dropping the 'hid_dev-&gt;driver' override and using
hid_register_driver()/hid_unregister_driver() instead. Alternatively, it
would have been possible to rely on the default handling but
HID_CONNECT_DEFAULT implies HID_CONNECT_HIDRAW and it doesn't seem to work
for mousevsc as-is.

Since the report buffer is used by all kinds of drivers in various ways, let's
zero-initialize it during allocation to make sure that it can't be ever used
to leak kernel memory via specially-crafted report.

The Thinkpad X1 Tablet Gen 3 keyboard has the same Lenovo specific quirks
as the original  Thinkpad X1 Tablet keyboard.

Add the PID for the "Thinkpad X1 Tablet Gen 3 keyboard" to the hid-lenovo
driver to fix the FnLock, Mute and media buttons not working.
