Exhibit b
Pretty much still looks like two independent patches squashed to one.

Since we're going to the trouble of changing all the calling conventions
I suspect we should just take this all the way and pass in state+crtc
rather than state+crtc_state.
See eg. commit 7451a074bf2f ("drm/i915: Change .crtc_enable/disable()
calling convention")
