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 (i386
defconfig) failed like this:

In file included from drivers/gpu/drm/i915/intel_guc.h:28:0,
                 from drivers/gpu/drm/i915/intel_uc.h:27,
                 from drivers/gpu/drm/i915/intel_uc.c:25:

Caused by commit

  6cc5ca768825 ("drm/i915: rename raw reg access functions")

I have reverted that commit and the following ones in the tree up to

  9511cb6481af ("drm/i915: Adding missing '; ' to ENGINE_INSTANCES")
