[alsa-devel] [RFC PATCH 6/7] ALSA: hda/hdmi - complete pcm_setup_pin without snd_pcm link

[Kai Vehmanen]

When used with e.g. SOF, the PCM entity is handled by ASoC and
there is no direct link from the HDA codec to the snd_pcm_t
object. Remaining configuration steps of hdmi_pcm_setup_pin()
should still be done in this case.
