Subject: [PATCH 0/7] ASoC: merge soc_pcm_open() rollback and soc_pcm_close()
Date: 28 Jul 2020 15:57:10 +0900
Message-ID: <87wo2oku0m.wl-kuninori.morimoto.gx@renesas.com> (raw)


Hi Mark

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;
	}

This kind of duplicated code can be a hotbed of bugs,
thus, this patch-set share soc_pcm_close() and rollback.

  ASoC: soc-dai: add mark for snd_soc_dai_startup/shutdown()
  ASoC: soc-link: add mark for snd_soc_link_startup/shutdown()
  ASoC: soc-component: add mark for soc_pcm_components_open/close()
  ASoC: soc-component: add mark for snd_soc_pcm_component_pm_runtime_get/put()
  ASoC: soc-pcm: add soc_pcm_clean() and call it from soc_pcm_open/close()
  ASoC: soc-pcm: remove unneeded dev_err() for snd_soc_dai_startup()
  ASoC: soc-pcm: remove unneeded dev_err() for snd_soc_component_module/open()
