[PATCH 5/5] platform/x86: uniwill-laptop: Handle super key lock events

From: Armin Wolf

Date: Tue Feb 10 2026 - 18:32:21 EST


On many devices, the user can toggle the super key lock state by
pressing Fn + F9. Forward the associated events to the super_key_lock
sysfs attribute as a poll notification.
