[ Upstream commit 2a2edfbbfee47947dd05f5860c66c0e80ee5e09d ]
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.
Will go drop it from 4.19.y, thanks. But is this ok also for 5.4.y?
thanks,
