ASoC: core: use less strict tests for dailink capabilities
Previous updates to set dailink capabilities and check dailink
capabilities were based on a flawed assumption that all dais support
the same capabilities as the dailink. This is true for TDM
configurations but existing configurations use an amplifier and a
capture device on the same dailink, and the tests would prevent the
card from probing.
This patch modifies the snd_soc_dai_link_set_capabilities()
helper so that the dpcm_playback (resp. dpcm_capture) dailink
capabilities are set if at least one dai supports playback (resp. capture).
Likewise the checks are modified so that an error is reported only
when dpcm_playback (resp. dpcm_capture) is set but none of the CPU
DAIs support playback (resp. capture).
Fixes: 25612477d20b5 ('ASoC: soc-dai: set dai_link dpcm_ flags with a helper')
Fixes: b73287f0b0745 ('ASoC: soc-pcm: dpcm: fix playback/capture checks')
