To support the DP-MST multiple streams via single connector feature, the HDMI driver was extended with the concept of backup PCMs. See commit 9152085defb6 ("ALSA: hda - add DP MST audio support").

This variable is not ever set in this patch, nor is it set elsewhere in 4.19-stable. This means this patch is not suitable for stable.
ack on that. In upstream this flag is only used by SOF (sound/soc/sof) currently, but SOF is not part of 4.19, so there are no users for this flag. Sorry for not catching this sooner.
Br, Kai
