This was merged through -tip, right? The DRM tree does not include the
initial patches, yet, so I'd recommend merging this through -tip
again. I've put hpa on CC for that. However, I cannot see where the
initial patch was sent to, so can you resent it properly to lkml,
please? And please also put the respective maintainers on CC.

Thanks
