Merge series "ASoC: compress: Support module_get on stream open" from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:

Hi,

SOF is marking all componet drivers with module_get_upon_open = 1 which works
fine with normal PCM streams, however on compressed side the module get upon
open is not supported. The module_get works when module_get_upon_open is not set
becasue the snd_soc_component_module_get_when_probe() will pass NULL for the
substream parameter of snd_soc_component_module_get().

In order to re-use the existing infrastructure for module_get, the proposal is
to convert the mark_module to void pointer (like the pm mark) and implement
matching code for the compressed open/free to pcm open/close.

Regards,
Peter
