Don't think is relevant, oter than why someone was looking at this code, but
this commit immediately trails a bunch of the vkms commits, and the crash/to
black screen happens right when amdgpu is attempting to automatically switch to
kms.

drm/fb-helper: Eliminate the .best_encoder() usage
Instead of using the .best_encoder() hook to figure out whether a given

just iterate over all the encoders for the connector, and then check
each crtc against each encoder's possible_crtcs bitmask.
