linux-next: build warning after merge of the drm-intel-fixes tree

Hi all,

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

drivers/gpu/drm/i915/intel_engine_cs.c: In function 'intel_engine_is_idle':
drivers/gpu/drm/i915/intel_engine_cs.c:1103:27: warning: unused variable 'dev_priv' [-Wunused-variable]
  struct drm_i915_private *dev_priv = engine->i915;
                           ^

Introduced by commit

  d9533f19d840 ("drm/i915: Hold a wakeref for probing the ring registers")
