Add changes to enable operating modes in the driver to allow the FW to
activate and retrieve data from relevant sensors. This enables the FW to
take necessary actions based on the operating modes.

Adds support for the XP-PEN Artist 22R Pro, including stylus, tablet frame
and pen pressure.
The tablet has 20 buttons, but need to be remapped in order since the
device reports invalid keycodes. Existing tablet functionality should
not be inhibited, as BTN0-8 is still used.
New initialization functions are added since the device differs slightly
from other UGEE v2 devices.

Syzkaller can create many uhid devices that trigger
repeated warnings like:
"hid-generic xxxx: unknown main item tag 0x0"
These messages can flood the system log, especially if a crash occurs
(e.g., with a slow UART console, leading to soft lockups). To mitigate
this, convert `hid_warn()` to use `dev_warn_ratelimited()`.
This helps reduce log noise and improves system stability under fuzzing
or faulty device scenarios.

During appletb_kbd_probe, probe attempts to get the backlight device
by name. When this happens backlight_device_get_by_name looks for a
device in the backlight class which has name "appletb_backlight" and
upon finding a match it increments the reference count for the device
and returns it to the caller. However this reference is never released
leading to a reference leak.
Fix this by decrementing the backlight device reference count on removal
via put_device and on probe failure.

in case we have GPIOLIB enabled the gpio pins are used
from the current driver as gpio pins. But may the gpio
functions of this pins are not enabled in the flash

In case CONFIG_IIO is not enabled we can prevent this

Commit fd2a9b29dc9c ("HID: wacom: Remove AES power_supply after extended
inactivity") introduced wacom_aes_battery_handler() which is scheduled
as a delayed work (aes_battery_work).
In wacom_remove(), aes_battery_work is not canceled. Consequently, if
the device is removed while aes_battery_work is still pending, then hard
crashes or "Oops: general protection fault..." are experienced when
wacom_aes_battery_handler() is finally called. E.g., this happens with
built-in USB devices after resume from hibernate when aes_battery_work
was still pending at the time of hibernation.
So, take care to cancel aes_battery_work in wacom_remove().

Commit 2f2bd7cbd1d1 ("hid: lenovo: Resend all settings on reset_resume
for compact keyboards") introduced a regression for ThinkPad TrackPoint
Keyboard II by removing the conditional check for enabling F7/9/11 mode
needed for compact keyboards only. As a result, the non-compact
keyboards can no longer toggle Fn-lock via Fn+Esc, although it can be
controlled via sysfs knob that directly sends raw commands.
This patch restores the previous conditional check without any
additions.

Plugging in a "Blue snowball" microphone always shows the
error 'No inputs registered, leaving', but the device functions as
intended.
When a HID device is started using the function hid_hw_start() and
the argument HID_CONNECT_DEFAULT it will try all various hid connect
requests. Not all devices will create an input device and so the
message is needlessly noisy. Decrease it to debug instead.

The Chicony Electronics HP 5MP Cameras (USB ID 04F2:B824 & 04F2:B82C)
report a HID sensor interface that is not actually implemented.
Attempting to access this non-functional sensor via iio_info causes
system hangs as runtime PM tries to wake up an unresponsive sensor.
Add these 2 devices to the HID ignore list since the sensor interface is
non-functional by design and should not be exposed to userspace.

When detecting an invalid list->hdev, the process needs to manually set
its state to TASK_RUNNING and exit. In the original code,
set_current_state() (which includes a memory barrier) is used here, but
it is immediately followed by a mutex_unlock() call. Since
mutex_unlock() internally includes a memory barrier, this ensures that
all modifications within the critical section (including the process
state) are visible to other CPUs. Therefore, replacing it with
__set_current_state() (without an implicit barrier) avoids redundant
memory barriers.

Wake-on-Touch (WoT) feature gives system the capability to wake from
sleep state by user touch event, it requires platform providing wake
GPIO through ACPI resource.
Intel UEFI provides a user setting to enable or disable THC device WoT
feature. If it's enabled, UEFI assigns an additional wake GPIO resource
to THC device ACPI configuration, facilitating system wakeup.
This patch provides helper APIs for THC device driver to query wake
GPIO resource, enable WoT feature and unconfigure WoT.
APIs added:
- thc_wot_config(): Query and configure wake-on-touch feature.
- thc_wot_unconfig(): Unconfig wake-on-touch feature.
