ack, that's a good catch. I'll keep this machine driver change in
the series anyways (I want to include all machine drivers that are in 
upstream kernel and have the HDMI setup code).

No info about this. The patch in my series for bxt_rt298 is a mechanical 
update (it has the HDMI code for hdac-hdmi and it can be used with SOF/GLK 
-> driver updated in the series).
