drm/i915: new warning (regression) in 3.7.10 and 3.8.3

drm/i915: new warning (regression) in 3.7.10 and 3.8.3

[Richard Cochran]

I have an Acer Aspire One netbook, and on it I get the following
warning when closing and opening the lid. I think this warning first
appeared in 3.7.

Does this need fixing? If so, who can do it?

Thanks,
Richard

Another pesky BIOS which changes the display state behind our back on lid
closing! Should be duct-tapped over with

But that warning was from a 3.8.3 kernel. Any other ideas?
