-    i915: Use struct_mutex to protect ring in GEM mode.
-    
-    In the conversion for GEM, we had stopped using the hardware lock to protect
-    ring usage, since it was all internal to the DRM now.  However, some paths
-    weren't converted to using struct_mutex to prevent multiple threads from
-    concurrently working on the ring, in particular between the vblank swap handler
-    and ioctls.
