I have a little flicker of doubt because these tend to end up being
passed into the core drm as well as used during modeset. Even looking
through the instances of drm_mode_set_crtcinfo() in the core, I'm left
no the wiser as to which functions expect crtc_* to be filled in. As far
I can see the only place where set_crtcinfo() must be called is prior to
the final modeset, and so the crtc_* values are only ever used on the
adjusted_mode. Hence why the drm usage leaves me slightly puzzled.
