Series acpi/x86: s2idle: move Display off/on calls outside suspend (fixes ROG Ally suspend) | expand

Commit Message

Antheas Kapenekakis Sept. 22, 2024, 5:22 p.m. UTC 
By moving the Display On/Off calls outside of the suspend sequence and
introducing a slight delay after Display Off, the ROG Ally controller
functions exactly as it does in Windows.

Therefore, remove the quirk that fixed the controller only when the
mcu_powersave attribute was disabled, while adding a large amount of
delay to the suspend and wake process.
