Subject: ALSA: hda/sigmatel: Convert to cdev-variant of mic-mute LED controls
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=23a2b46966bde1e54a7b67e4968554905d71cad5;p=linux.git

ALSA: hda/sigmatel: Convert to cdev-variant of mic-mute LED controls

This patch converts the remaining user of
snd_hda_gen_add_micmute_led() in IDT/Sigmatel codec driver into the
new snd_hda_gen_add_micmute_led_cdev().
