ASoC component open/close and snd_soc_component_module_get/put are called independently for each component-substream pair, so the logic in the reverted patch was not sufficient and led to PCM playback and module unload errors.
But, unfortunately I don't want spaghetti error handling code again. I think we can solve it if we can *count* open / module ? Can you please test this patch ?
I tested and this version works as well, so: Reviewed-by: Kai Vehmanen kai.vehmanen@linux.intel.com
... but, but, I have some doubts about th "opened" tracking as a solution.
A single counter will track the overall number of component-substream combinations, but if we have bugs in calling code and e.g. same component-substream is passed multiple times to open or close, the the single counter will go out of sync.
So if the primary problem is the messy rollback in case one open fails, what if we do the rollback directly in soc_pcm_components_open() and do not add any additional tracking..?
Let me send a proposal patch for that.
