Now, soc_compr_open/free() are handling 1) snd_soc_dai_compr_startup/shutdown() 2) snd_soc_component_compr_open/free() 3) snd_soc_link_compr_startup/shutdown() Now, 1) to 3) are handled. This patch adds new soc_compr_clean() and call it from soc_compr_open() as rollback, and from soc_compr_free_free() as normal close handler.
