ASoC: soc-component: add mark for snd_soc_link_compr_startup/shutdown()
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; } The difference is soc_compr_free() 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_compr_free() and rollback. 1) snd_soc_dai_compr_startup/shutdown() 2) snd_soc_component_compr_open/free() => 3) snd_soc_link_compr_startup/shutdown() This patch is for 3) snd_soc_link_compr_startup/shutdown() and adds new cstream mark. It will mark cstream when startup() was suceeded. If rollback happen *after* that, it will check rollback flag and marked cstream. It cares *previous* startup() only now, but we might want to check *whole* marked cstream in the future. This patch is using macro so that it can be easily adjust to it.
