ASoC: soc-dai: add snd_soc_dai_active()
Current snd_soc_dai_action() is updating
dai->stream_active for Playback/Capture (A),
dai->active for DAI (B)
void snd_soc_dai_action(struct snd_soc_dai *dai,
int stream, int action)
{
(A) dai->stream_active[stream] += action;
(B) dai->active += action;
dai->component->active += action;
}
But, these are very verbose, because we can calculate
DAI active from stream_active.
This patch adds snd_soc_dai_active() which calculate
DAI active from DAI stream_active.
