drm/nv50-/kms: reject attempts at flipping to incompatible framebuffer Looks like a userspace bug can trigger this somehow during a mode switch, causing: EVO complaint -> semaphores get out of sync -> entire display stalled. We likely want to be even stricter than this (or at least deal better if EVO rejects our request), but I'll save that for the drm_plane/atomic conversion and just fix the bug that I already know can be triggered.
