So does the fix help from 107738 help? My main question to the reported of this
bug was that is this really reproducible with most recent drm-tip.

If so and the fix I attached really helps, it means that there is an internal
logic issue with dp mst handling, which makes primary reference assigned to
NULL,
even though it is still used. 
So even if my fix helps, there will be more serious fixes needed.
