[PATCH 5/7] ASoC: soc-pcm: goto error after trying all component open

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

soc_pcm_components_open() might goto error process *during* opening
component loop.
In such case, fallback process need to care about operated/non-operated
component.

But, if it goto error process *after* loop even though error happen
during loop, it don't need to care about operated/non-operated.
In such case code can be more simple.
This patch do it. And this is prepare for soc_snd_open() cleanup
