From: Praveen Paneri <praveen.paneri@xxxxxxxxx> i915_gem_shrink_all() will scan the bound list only if device is not suspended but in OOM scenarios it becomes absolutely necessary to release as much memory as possible. So, adding rpm get/put in i915_shrinker_oom() to ensure shrinking of bound objects in OOM scenario.
