Merge series "ASoC: merge soc_compr_open() rollback and soc_compr_free()" from Kuninori Morimoto <[email protected]>:

Hi Mark

soc_compr_open() does rollback when failed (A),
but, it is almost same as soc_compr_free().

	static int soc_compr_open(xxx)
	{
		...
		if (ret < 0)
			goto xxx_err;
		...
		return 0;

 ^	machine_err:
 |		...
 |	out:
(A)		...
 |	pm_err:
 |		...
 v		return ret;
	}

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

Kuninori Morimoto (5):
  ASoC: soc-compress: move soc_compr_free() next to soc_compr_open()
  ASoC: soc-dai: add mark for snd_soc_dai_compr_startup/shutdown()
  ASoC: soc-component: add mark for snd_soc_component_compr_open/free()
  ASoC: soc-component: add mark for snd_soc_link_compr_startup/shutdown()
  ASoC: soc-compress: add soc_compr_clean() and call it from soc_compr_open/free()
