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

    drm/fb-helper: Eliminate the .best_encoder() usage

    Instead of using the .best_encoder() hook to figure out whether a given
    connector+crtc combo will work, let's instead do what userspace does and
    just iterate over all the encoders for the connector, and then check
    each crtc against each encoder's possible_crtcs bitmask.

    v2: Avoid oopsing on NULL encoders (Daniel)
