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.
