+Subject: drm/amdgpu: fix error handling in amdgpu_bo_list_get()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit

+From: Christian König <christian.koenig@amd.com>
+
+commit 12f76050d8d4d10dab96333656b821bd4620d103 upstream.
+
+We should not leak the pointer where we couldn't grab the reference
+on to the caller because it can be that the error handling still
+tries to put the reference then.
