So far, the hda_codec object kept the hda_pcm list in an array, and the codec driver was expected to assign the array. However, this makes the object life cycle management harder, because the assigned array is freed at the codec driver detach while it might be still accessed by the opened streams. In this patch, we allocate each hda_pcm object dynamically and manage it as a linked list. Each object has a kref refcount, and both the codec driver binder and the PCM open/close touches it, so that the object won't be freed while in use. Signed-off-by: Takashi Iwai <tiwai@suse.de> |
