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

  3b3f1650b1ca ("drm/i915: Allocate intel_engine_cs structure only for the enabled engines")

interacting with some other commits that were merged without fixes being applied (probably) in commit

  06a75ace46e2 ("Merge tag 'gvt-next-2016-10-14' of https://github.com/01org/gvt-linux into drm-intel-next-queued")

I have used the version of the drm-intel tree from next-20161017 for
today.
