[PATCH AUTOSEL 5.4 07/11] HID: add ALWAYS_POLL quirk for Apple kb

[Sasha Levin]

From: Oliver Neukum <oneukum@suse.com>

[ Upstream commit c55092187d9ad7b2f8f5a8645286fa03997d442f ]

These devices disconnect if suspended without remote wakeup. They can operate
with the standard driver.

[PATCH AUTOSEL 5.4 08/11] HID: hid-asus: reset the backlight brightness level on resume

[Sasha Levin]

From: Denis Benato <benato.denis96@gmail.com>

[ Upstream commit 546edbd26cff7ae990e480a59150e801a06f77b1 ]

Some devices managed by this driver automatically set brightness to 0
before entering a suspended state and reset it back to a default
brightness level after the resume:
this has the effect of having the kernel report wrong brightness
status after a sleep, and on some devices (like the Asus RC71L) that
brightness is the intensity of LEDs directly facing the user.

Fix the above issue by setting back brightness to the level it had
before entering a sleep state.

[PATCH AUTOSEL 5.4 09/11] HID: multitouch: Add quirk for HONOR GLO-GXXX touchpad

[Sasha Levin]

From: Aoba K <nexp_0x17@outlook.com>

[ Upstream commit 9ffccb691adb854e7b7f3ee57fbbda12ff70533f ]

Honor MagicBook 13 2023 has a touchpad which do not switch to the multitouch
mode until the input mode feature is written by the host.  The touchpad do
report the input mode at touchpad(3), while itself working under mouse mode. As
a workaround, it is possible to call MT_QUIRE_FORCE_GET_FEATURE to force set
feature in mt_set_input_mode for such device.

The touchpad reports as BLTP7853, which cannot retrive any useful manufacture
information on the internel by this string at present.  As the serial number of
the laptop is GLO-G52, while DMI info reports the laptop serial number as
GLO-GXXX, this workaround should applied to all models which has the GLO-GXXX.
