Series ALSA: hda: Use LED classdev for mute controls consistently | expand

Commit Message

Takashi Iwai June 18, 2020, 11:08 a.m. UTC 
Now all users of the old snd_hda_gen_add_micmute_led() have been
converted to the new LED-classdev variant, and we can make it local,
and remove the unused hda_gen_spec.micmute_led.update callback field.
