Since you mention that after rebooting it assigned the right trigger
that is expected - the triigers are coming from keyboard.c which is
built-in, not a module.

On Debian and Ubunty the keycode emitted by CapsLock ke=y is CtrlL_Lock
for whatever reason, so CapsLock LED does not light up by default
(neither with these patcher nor without them). If you change setkeycodes
to assign CapsLock to keycode 58 it should work. Or set trigger for the
led to "kbd-ctrlllock".

Thanks.
