Hi,
Some MST fixups that landed in 6.3-rc1 were CC to stable and successfully
applied to 6.2.y, but failed to apply to 6.1.y even though they are needed
there as well.
They fail to apply due to this commit missing in 6.1.y:
commit 8c7d980da9ba ("drm/nouveau/disp: move DP MST payload config method")
Backporting that is a rabbit hole of other work and makes this no longer
viable for stable, so instead hand modify
commit e761cc20946a ("drm/display/dp_mst: Handle old/new payload states in drm_dp_remove_payload()")
for the missing contextual changes in 6.1.y in nouveau.
I've tested that these work on a Rembrandt laptop connected to WD19TB
with two monitors connected.
