commit 46c7b901e2a03536df5a3cb40b3b26e2be505df6 upstream.
The spcm->stream[substream->stream].substream is set during open and was left untouched. After the first PCM stream it will never be NULL and we have code which checks for substream NULLity as indication if the stream is active or not. For the compressed cstream pointer the same has been done, this change will correct the handling of PCM streams.
