Thanks for the report.

Patch fa57924c76d995 ("drm/amd/display: Refactor function dm_dp_mst_is_port_support_mode()") is kind of correcting problems causing by commit: 4df96ba6676034 ("drm/amd/display: Add timing pixel encoding for mst mode validation")

Sorry if it misses fixes tag and would suggest to backport to fix it. Thanks!

Greg, seem it would be wise to pick up fa57924c76d995 for 6.10.y as well, despite a lack of Fixes or stable tags.

Ciao, Thorsten

The issue is that the fixing commit does not apply to the 6.10 series without conflict and the offending commit does not revert cleanly aswell.

Cheers, Chris
