ASoC: soc-pcm: add soc_pcm_clean() and call it from soc_pcm_open/close()
soc_pcm_open() does rollback when failed (A), but, it is almost same as soc_pcm_close(). static int soc_pcm_open(xxx) { ... if (ret < 0) goto xxx_err; ... return 0; ^ config_err: | ... | rtd_startup_err: (A) ... | component_err: | ... v return ret; } The difference is soc_pcm_close() is for all dai/component/substream, rollback is for succeeded part only. This kind of duplicated code can be a hotbed of bugs, thus, we want to share soc_pcm_close() and rollback. Now, soc_pcm_open/close() are handling 1) snd_soc_dai_startup/shutdown() 2) snd_soc_link_startup/shutdown() 3) snd_soc_component_module_get/put() 4) snd_soc_component_open/close() 5) pm_runtime_put/get() Now, 1) to 5) are handled. This patch adds new soc_pcm_clean() and call it from soc_pcm_open() as rollback, and from soc_pcm_close() as normal close handler. One note here is that it don't need to call snd_soc_runtime_deactivate() when rollback case, because it will be called without snd_soc_runtime_activate(). It also don't need to call snd_soc_dapm_stream_stop() when rollback case.
