[PATCH 00/10] ALSA/ASoC: hda: cleanup sound/hda/ext code

[Pierre-Louis Bossart]

The code in sound/hda/ext can be cleaned-up. This patchset suggests a
more consistent use of prefixes and variable names. It also removes
useless code, uses helpers when possible, and clarifies an incorrect
assumption that SPIB/DRMS capabilities are tied to Intel multi-link
and DSP extensions (they are not).

This is a rather invasive set of changes touching sound/hda,
sound/soc/intel/skylake, sound/soc/intel/avs and sound/soc/sof/intel,
but there should be no change in terms of functionality.

I would recommend merging these changes through the ASoC tree.

Pierre-Louis Bossart (10):
  ALSA: hda: ext: hdac_ext_controller: use helpers in loop
  ALSA: hda: ext: hda_ext_controller: use hlink variable/parameter
  ASoC: SOF: Intel: hda-dai: use hlink variable/parameter
  ALSA/ASoC: hda: clarify bus_get_link() and bus_link_get() helpers
  ALSA/ASoC: hda: ext: add 'ext' prefix to snd_hdac_link_free_all
  ALSA/ASoC: hda: ext: remove 'link' prefix for stream-related
    operations
  ALSA/ASoC: hda: ext: add 'bus' prefix for multi-link stream setting
  ALSA: hda: ext: reduce ambiguity between 'multi-link' and 'link' DMA
  ALSA: hda: hdac_ext_controller: remove useless loop
  ALSA/ASoC: hda: move SPIB/DRMS functionality from ext layer
