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() This patch is for 2) snd_soc_link_startup/shutdown(), and adds new substream mark. It will mark substream when startup was suceeded. If rollback happen *after* that, it will check rollback flag and marked substream. It cares *previous* startup() only now, but we might want to check *whole* marked substream in the future. This patch is using macro so that it can be easily adjust to it.
