[PATCH 0/6] ASoC: merge soc_pcm_hw_param() rollback and soc_pcm_hw_free()

29 Sep 2020


      Hi Mark
soc_pcm_hw_params() does rollback when failed (A),
but, it is almost same as soc_pcm_hw_free().
static int soc_pcm_hw_params(xxx)
    {
    	...
    	if (ret < 0)
    		goto xxx_err;
    	...
    	return ret;
^	component_err:
 |		...
 |	interface_err:
(A)		...
 |	codec_err:
 |		...
 v		return ret;
    }
This kind of duplicated code can be a hotbed of bugs,
thus, this patch-set share soc_pcm_hw_free() and rollback.
Kuninori Morimoto (6):
  ASoC: soc.h: remove for_each_rtd_dais_rollback()
  ASoC: soc-pcm: move soc_pcm_hw_free() next to soc_pcm_hw_params()
  ASoC: soc-link: add mark for snd_soc_link_hw_params/free()
  ASoC: soc-component: add mark for snd_soc_pcm_component_hw_params/free()
  ASoC: soc-dai: add mark for snd_soc_dai_hw_params/free()
  ASoC: soc-pcm: add soc_pcm_hw_clean() and call it from soc_pcm_hw_params/free()
