[PATCH 4/4] acpi/x86: s2idle: Add a quirk for ASUS TUF Gaming A17 FA707RE

From: Mario Limonciello
Date: Fri Sep 09 2022 - 14:06:03 EST


ASUS TUF Gaming A17 FA707RE has problems with ACPI events after
s2idle resume. It's from a missing call to an ASL method in AMD
the s2idle calling path. Force the system to use the Microsoft
Modern Standby calling path instead.
