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

Hi all,

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

Caused by commit

  93ca7e006670 ("drm/i915: Use the per-plane rotation property")

interacting with commit

  55b8f2a76dff ("drm/i915: Make INTEL_GEN only take dev_priv")

from the drm-intel tree.

I added this merge fix patch:
