If we have this patch in 5.10: drm/amd/display: disable stream if pixel clock changed with link active We need to backport: 1. drm/amd/display: Fix module load hangs when connected to an eDP (for DCN) 2. drm/amd/display: Add get_dig_frontend implementation for DCEx (for DCEx - we still need Boris feedback) > Depending on the patches, it might be easier to just revert this for > 5.10 and apply the proper fix for 5.11. I like this approach; we can apply the proper fix on 5.11.
