Chris Wilson 947fdaadf0 drm/i915: Do not attempt to re-enable an unconnected primary plane ... Due to user fudging (for instance using video=VGA-1:e with FBDEV=n) we can attempt to reset an inconsistent CRTC that is marked as active but has no assigned fb. It would be wise to fix this earlier, but the long term plan is to have primary and secondary planes associated with a CRTC, in which crtc->fb being NULL will be expected. So for a quick short term fix with pretensions of grandeur, just check for a NULL fb during GPU reset and ignore the plane restoration. This fixes a potential hard hang (a panic in the panic handler) following a GPU hang.
