From fe1a162191a59cbfd3f917e92cdb2d5de996a8a0 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 18 Jun 2020 13:08:36 +0200 Subject: ALSA: hda: generic: Drop the old mic-mute LED hook 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.
