Subject: [PATCH 1/5] platform/x86: uniwill-laptop: Rename FN lock and super key lock attrs
It turns out that both sysfs attributes actually directly control
the FN lock status/super key enable status, rather than the
triggering of the associated events. This behavior was first observed
on a Tuxedo notebook and was belived to be a hardware quirk.
However, it seems that i simply misunderstood the manual of the
OEM software for Intel NUC devices. The correct behavior is:
- fn_lock_toggle_enable enables/disables FN lock mode
- super_key_toggle_enable enables/disables the super key
Rename both sysfs attributes to avoid confusing users.
Fixes: d050479693bb ("platform/x86: Add Uniwill laptop driver")
