[PATCH 0/5] uniwill-laptop: Input-related improvements

From: Armin Wolf

Date: Tue Feb 10 2026 - 18:30:13 EST


This patch series contains a set of input-related improvements
for the uniwill-laptop driver. The first patch renames the
"fn_lock_toggle_enable" and "super_key_toggle_enable" sysfs attributes
after it was discovered that the underlying hardware works differently
than previously thought. This technically breaks user space
applications using those sysfs attributes, but AFAIK no such users
currently exist.

The next two patches fix a potential crash and an issue with the fn
lock status not being updated when using a key combination. The
remaining patches ensure that when the users changes the fn lock
status or enables/disables the super key using a key combination, a
poll notification is being issued on the appropriate sysfs attr.

Armin Wolf (5):
platform/x86: uniwill-laptop: Rename FN lock and super key lock attrs
platform/x86: uniwill-laptop: Fix crash on unexpected battery event
platform/x86: uniwill-laptop: Mark FN lock status as being volatile
platform/x86: uniwill-laptop: Handle FN lock event
platform/x86: uniwill-laptop: Handle super key lock events
