Veronika Schwan reported an MST regression introduced in 6.2.10 by a backport of commit d7b5638bd337 ("drm/amd/display: Take FEC Overhead into Timeslot Calculation") into stable.
This fix was actually correct, but there was a related fix that should have come back as well. This is a backport of that fix for 6.2.y and 6.1.y.
Due to another code change, it's not a straight backport, but it's just a one line change from context that changed in other patches. Wayne Lin (1): drm/amd/display: Pass the right info to drm_dp_remove_payload
