[alsa-devel] [PATCH RFC 01/26] ALSA: hda - Simplify bound-beep mute control for ALC268

[Takashi Iwai]

The beep mute switch for ALC268 needs to touch two NIDs, and we used
to apply the bind-mixer stuff.  But the use case for ALC268 is fairly
easy to convert to an open-code in a shorter form.  Since this is the
only user of the bind-ctls, we can clean up the common helper codes
later.
