Merge series "ASoC: Fix dailink checks for DPCM" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

We've had a couple of changes that introduce regressions with the
multi-cpu DAI solutions, and while trying to fix them we found
additional inconsistencies that should also go to stable branches.

Bard Liao (1):
  ASoC: core: only convert non DPCM link to DPCM link

Pierre-Louis Bossart (3):
  ASoC: soc-pcm: dpcm: fix playback/capture checks
  ASoC: Intel: boards: replace capture_only by dpcm_capture
  ASoC: SOF: nocodec: conditionally set dpcm_capture/dpcm_playback flags
