Cover letter [PATCH v2 0/2] drm/msm: fix CTL/LM swap on color management changes
Closing the lid of an X1E laptop under GNOME with an external display attached moves the still active external CRTC to other CTL/LM blocks without a modeset, which ends in SMMU faults and a hung display pipeline. Patch 1 fixes that in DPU. Patch 2 removes the CTM-only allow_modeset hack in msm_atomic_check(), which patch 1 makes redundant.
