dmesg from 3.12-rc1 with drm debug

There is a seemingly harmless WARNING on every bootup on my PC with DP monitor.
It appeared between 3.6 and 3.7, first reported on LKML
https://lkml.org/lkml/2012/11/12/343 in Nov 2012. Later it was added to a
bugzilla bug https://bugzilla.kernel.org/show_bug.cgi?id=52061 where the old
dmesgs from 3.6 and 3.7 are still present. This bug came out to be something
different so I am resubmitting it as a separate bug on Ironlake.

I retested it with 3.11 and 3.12-rc1, it is still there, dmesg with drm debug
from 3.12-rc1-00101-ged24fee is attached.
