[PATCH v4 0/4] uniwill-laptop: Input-related improvements

[Armin Wolf <W_Armin@gmx.de>]

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 patch ensurea that when the users changes the fn lock
status using a key combination, a poll notification is being issued
on the appropriate sysfs attr.

Tested on a TUXEDO InfinityBook Pro 15 Gen 10 AMD (whitelist entry
comes next).

Changes since v3:
- drop last patch, because it turned out that all super key events
  are also send by the EC when the super key is enabled/disabled
  using the sysfs attribute

Changes since v2:
- rename UNIWILL_OSD_SUPER_KEY_LOCK_CHANGED
- do no use UNIWILL_OSD_SUPER_KEY_LOCK_ENABLE and
  UNIWILL_OSD_SUPER_KEY_LOCK_DISABLE events for triggering
  the poll notification

Changes since v1:
- update admin-guide for uniwill laptops
- rename UNIWILL_OSD_SUPER_KEY_LOCK_ENABLE and
  UNIWILL_OSD_SUPER_KEY_LOCK_DISABLE
- fix small issue in commit description of patch 5
