Hi,
There is a bug present in 6.2.y and 6.1.y where if a dock that supports MST is unplugged during suspend it's not possible to get MST working after resume. This is because the cleanup/error path doesn't actually clear the MST tree.
It's fixed in 6.3 with:
3f6752b4de41 ("drm/amd/display: Clear MST topology if it fails to resume")
Can this please be backported to 6.2.y and 6.1.y?
Thanks,
