Subject: ALSA: hda - Fix missing mute controls for CX5051
From: Takashi Iwai <tiwai@xxxxxxx>
commit f69910ddbd8c29391958cf82b598dd78fe5c8640 upstream.
We've added a fake mute control (setting the amp volume to zero) for
CX5051 at commit [3868137e: ALSA: hda - Add a fake mute feature], but
this feature was overlooked in the generic parser implementation. Now
the driver lacks of mute controls on these codecs.
The fix is just to check both AC_AMPCAP_MUTE and AC_AMPCAP_MIN_MUTE
bits in each place checking the amp capabilities.
