ASoC: soc-pcm: merge playback/cature_active into stream_active
DAI has playback_active and capture_active to care usage count. OTOH, we have SNDRV_PCM_STREAM_PLAYBACK/CAPTURE. But because of this kind of implementation mismatch, ALSA SoC has many verbose code. To solve this issue, this patch merge playback_active/capture_active into stream_active[2]; Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Reviewed-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com> Reviewed-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Link: https://lore.kernel.org/r/875zg5botu.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
