For the record, this patch generates compilation warnings when applied
on its own:

drivers/gpu/drm/i915/intel_runtime_pm.c:368:13: warning: ‘gen9_enable_dc5’ defined but not used [-Wunused-function]
 static void gen9_enable_dc5(struct drm_i915_private *dev_priv)
             ^
drivers/gpu/drm/i915/intel_runtime_pm.c:386:13: warning: ‘gen9_disable_dc5’ defined but not used [-Wunused-function]
 static void gen9_disable_dc5(struct drm_i915_private *dev_priv)
             ^

Generally speaking, in a series, each step should compile without warning and
result in a working driver (for bisectability).
