Merge series "ASoC: SOF: cleanups and improvements" from Pierre-Louis Bossart... 

Merge series "ASoC: SOF: cleanups and improvements" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

Couple of small patches to improve error handling, inits, logs.

Hope we can have this for 5.7?

Guennadi Liakhovetski (2):
  ASoC: SOF: (cosmetic) use for_each_pcm_streams() in sof_dai_load()
  ASoC: SOF: fix uninitialised "work" with VirtIO

Kai Vehmanen (2):
  ASoC: SOF: Intel: hda: do not leave clock gating off upon error
  ASoC: SOF: Intel: hda: call codec wake at chip init

Ranjani Sridharan (1):
  ASoC: SOF: Intel: hda: Improve DSP state logging
