>Subject: [PATCH] drm/i915: again disable all outputs at load time
>
>This has been broken in the modeset rework and can lead to hangs of
>the display block, ultimately leading to the hw's untimely demise in a
>unrecoverable hang (on gen2/3 where gpu reset isn't available).

>v2: Rebase on top of 3.7.
