Am I right in assuming you took this patch?

I expect that new code using udelay was added to the amd tree,
and when merged with drm-misc-next it failed, because drm-misc-next no
longer had drmP.h included so no implicit include of delay.h

The root cause was that my original patchset should have been based
on the amd tree, and applied there :-(
