[PATCH 0/8] ALSA: hda: document/simplify hdac_ext handling

[Pierre-Louis Bossart]

This sound/hda/ext library is a confusing magic black box that very
few understand. It needn't be that way, we can document/simplify and
make the code clearer.

Pierre-Louis Bossart (8):
  ALSA: hda: make snd_hdac_stream_clear() static
  ALSA: hda: document state machine for hdac_streams
  ALSA: hda: ext: make snd_hdac_ext_stream_init() static
  ALSA: hda: Use hdac_ext prefix in snd_hdac_stream_free_all() for
    clarity
  ALSA: hda: add snd_hdac_stop_streams() helper
  ALSA: hda: ext: simplify logic for stream assignment
  ALSA: hda: ext: fix locking in stream_release
  ALSA: hda: ext: remove always-true conditions on host and link release
