Merge tag 'leds-5.5-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-leds
 
Pull LED fixes from Pavel Machek:
 "Jacek's fix for an uninitialized gpio label is why I'm requesting this
  pull; it fixes regression in debugging output in sysfs. Others are
  just bugfixes that should be safe.

  Everything has been in -next for while"
