From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>
__rcu annotation is needed to avoid the sparse warnings such as:
.../i915_drm_client.c:92:9: sparse: sparse: incompatible types in comparison expression (different address spaces):
.../i915_drm_client.c:92:9: sparse: struct list_head [noderef] __rcu *
.../i915_drm_client.c:92:9: sparse: struct list_head *
