Merge tag 'topic/mst-bw-check-fixes-for-airlied-2020-03-12-2' of git://anongit.freedesktop.org/drm/drm-misc into drm-fixes
UAPI Changes: None
Cross-subsystem Changes: None
Core Changes: Fixed regressions introduced by commit cd82d82cbc04
("drm/dp_mst: Add branch bandwidth validation to MST atomic check"),
which would cause us to:
* Calculate the available bandwidth on an MST topology incorrectly, and
as a result reject most display configurations that would try to enable
more then one sink on a topology
* Occasionally expose MST connectors to userspace before finishing
probing their PBN capabilities, resulting in us rejecting display
configurations because we assumed briefly that no bandwidth was
available
Driver Changes: None
