gpiolib: acpi: Add a quirk for Acer Nitro V15
[ Upstream commit 9ab29ed505557bd106e292184fa4917955eb8e6e ]
It is reported that on Acer Nitro V15 suspend only works properly if the
keyboard backlight is turned off. In looking through the issue Acer Nitro
V15 has a GPIO (#8) specified in _AEI but it has no matching notify device
in _EVT. The values for GPIO #8 change as keyboard backlight is turned on
and off.
This makes it seem that GPIO #8 is actually supposed to be solely for
keyboard backlight. Turning off the interrupt for this GPIO fixes the issue.
Add a quirk that does just that.
