I support the goal of moving towards drm_connector_init_with_ddc(), and
after that, to drm_edid_read() where applicable.

I admit to being a notch less diligent in reviewing all the details of
legacy encoder code, but there are no obvious mistakes here that I could
spot, and overall it makes sense.

Thanks,
Jani.
