Thank you guys for reviewing and taking the patch.

Now, while I was looking at the uses of i915_add_request(), I found
the following code :

                        ret = i915_gem_flush_ring(ring, 0,
I915_GEM_GPU_DOMAINS);
                        request = kzalloc(sizeof(*request), GFP_KERNEL);
                        if (ret || request == NULL ||
                            i915_add_request(ring, NULL, request))
                            kfree(request);
