Hi
A few chunks down below:
2013/2/21 Daniel Vetter <daniel.vetter at ffwll.ch>:
> This is used way too often in the enable/disable paths. And will
> be even more useful in the future.
>
> Note that correct semantics of this change highly depend upon
> correct updating of intel_crtc->config: Like with all other
> modeset state, we need to call ->disable with the old config,
> but ->mode_set and ->enable with the new config.
>
> v2: Do not yet use the flag in the ->disable callbacks - atm we don't
> yet have support for the information stored in the pipe_config in the
> hw state readout code, so this will be wrong at boot-up/resume.
>
> v3: Rebased on top of the hdmi/dp ddi encoder merging.
>
> v4: Fixup stupid rebase error which lead to a NULL vfunc deref.
>
> v5: On haswell the VGA port is on the PCH!

You forgot to kill haswell_crtc_driving_pch and replace its usage
inside haswell_crtc_disable.
