[alsa-devel] [PATCH v2 4/7] ASoC: soc-pcm: goto error after trying for_each_rtd_codec_dai

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

soc_pcm_open() might goto error process *during* for_each_rtd_codec_dai.
In such case, fallback process need to care about operated/non-operated
codec dai.

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
