Subject: ALSA: hda - Add spec->vmaster_mute_enum flag to generic parser
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fd25a97a97c78e7f09b0b3069a40bf7671654366;p=openwrt%2Fstaging%2Fblogic.git

ALSA: hda - Add spec->vmaster_mute_enum flag to generic parser

Add a flag to indicate whether the vmaster mute hook enum is exposed
or not.  Conexant codecs may want not to expose the control depending
on the model.
