[PATCH 2/7] platform/x86: uniwill-laptop: Handle screen-related events
From: Armin Wolf
Date: Sat May 30 2026 - 13:09:11 EST
The EC will report event 0xCC on some devices when the screen
has been enabled/disabled during resume/suspend. Ignore this
event because it is currently unused by the driver.
