Currently stream destructor in each driver has a problem to be called in a context in which sound card object is released, because the destructors call amdtp_stream_pcm_abort() and touch PCM runtime data. The PCM runtime data is destroyed in application's context with snd_pcm_close(), on the other hand PCM substream data is destroyed after sound card object is released, in most case after all of ALSA character devices are released. When PCM runtime is destroyed and PCM substream is remained, amdtp_stream_pcm_abort() touches PCM runtime data and causes Null-pointer-dereference. This commit changes stream destructors and allows each driver to call it after releasing runtime.
