ASoC: soc-pcm: call snd_soc_component_open/close() once
Current soc_pcm_open() calls snd_soc_component_open() under loop. Thus, it needs to care about opened/not-yet-opened Component. But, if soc-component.c is handling it, soc-pcm.c don't need to care about it. This patch adds opened flag to soc-component.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> Reviewed-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Link: https://lore.kernel.org/r/874kvzcey1.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
