Merge series "ASoC: SOF: preparatory patches" from Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>:

Browse source 
2 preparatory patches for the SOF virtualisation work. No functional
changes, only some code refactoring and exporting of helper functions.

v2: rebase, no changes otherwise.

Thanks
Guennadi

Guennadi Liakhovetski (2):
  ASoC: (cosmetic) simplify dpcm_prune_paths()
  ASoC: export DPCM runtime update functions
