"drm/amd/display: Add polling method to handle MST reply packet" was intended to be backported to kernel 6.1 to solve usage of some non-spec compliant MST hubs.
This series has a variety of dependencies across amdgpu_dm though, so the backport requires several manual fixups to avoid hitting file and symbol renames.
Details of individual changes are in the commit message for each patch.
