Hi Jesse,

	I think I had replied the "[PATCH 2/2] drm/i915: only set the intel_crtc DPMS mode	to on if the mode set succeeded". And I'll replay it again.

	And confirm with you. When I tested about 3-pipe feature, I used your branch "ivb-3-pipe", which contain 4 commits in all. And 2 patches for Xserver, one is on the upstream and the other is attached. So that is to say, 3 commits on branch "ivb-3-pipe" and a xserver patch are needed to put on the upstream. Right?

Thanks
Yi
