Oh sorry again for this regression, Kai. Originally my patches were developed with slightly older code which doesn't have your commit 2a2edfbbfee4 (ALSA: hda/hdmi - implement mst_no_extra_pcms flag), when I merge them with tot I did not notice codec->mst_no_extra_pcms mode. This patch looks good to me.
