ASoC: soc-pcm: call snd_soc_dai_startup()/shutdown() once
Current soc_pcm_open() calls snd_soc_dai_startup() under loop. Thus, it needs to care about started/not-yet-started codec DAI. But, if soc-dai.c is handling it, soc-pcm.c don't need to care about it. This patch adds started flag to soc-dai.h, and simplify soc-pcm.c. This is one of prepare for cleanup soc-pcm-open() Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/875zgfcey5.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
