Subject: linux-next: build failure after merge of the drm-intel tree

Hi all,

After merging the drm-intel tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commit a25ca17c1eac ("drm/i915: Do not dereference pointers
from ring buffer in evict event").

I have used the drm-intel tree from next-20140318 for today.
