From: Nenghua Cao <nhcao at marvell.com>
V2 -> V1:
Removes the flag and update DPCM always when mixer/mux changes, according
to Takashi's and Mark's suggestion.
>> Usually backward compatibility is concerned when something new breaks
>> the existing ones. In your case, always updating DPCM would work,
>> too, even without an extra flag; it's just suboptimal.
>Right, and if we have separate versions then at some point we'll end up
>having to define DPCM versions of everything which is going to get
>tedious and error prone.
V1 -> V0:
refined patch, and add flag into soc_mixer_control and soc_enum
instead of the alsa core, according to Takashi's suggestion.
> You don't need to extend the ALSA core API for such a purpose. It's
> ASoC-specific, so rather extend struct soc_mixer_control instead, if
> such a new flag is really needed.
