snd_soc_dai_digital_mute() is internally using both
mute_stream() (1) or digital_mute() (2), but the difference between
these 2 are only handling direction.
We can merge digital_mute() into mute_stream

	int snd_soc_dai_digital_mute(xxx, int direction)
	{
		...
		else if (dai->driver->ops->mute_stream)
(1)			return dai->driver->ops->mute_stream(xxx, direction);
		else if (direction == SNDRV_PCM_STREAM_PLAYBACK &&
			 dai->driver->ops->digital_mute)
(2)			return dai->driver->ops->digital_mute(xxx);
		...
	}

For hdmi-codec, we need to update struct hdmi_codec_ops,
and all its users in the same time.

Thanks for this clean-up Morimoto-san.

One question: in all the codec changes the return is now 0.

But in the previous implementation based on digital_mute, when the wrong 
direction was used it would have been -ENOTSUPP.

int snd_soc_dai_digital_mute(struct snd_soc_dai *dai, int mute,
			     int direction)
{
	int ret = -ENOTSUPP;

	if (dai->driver->ops &&
	    dai->driver->ops->mute_stream)
		ret = dai->driver->ops->mute_stream(dai, mute, direction);
	else if (direction == SNDRV_PCM_STREAM_PLAYBACK &&
		 dai->driver->ops &&
		 dai->driver->ops->digital_mute)
		ret = dai->driver->ops->digital_mute(dai, mute);

<<< none of the branches taken for capture + digital_mute supported, so 
return -ENOTSUPP.

	return soc_dai_ret(dai, ret);
}

Was this change intentional?

We also want to check why this return value is only tested in 
soc-dapm.c, if this digital_mute can fail then we are missing tests left 
and right - maybe that's a follow-up change?
