+Subject: [PATCH] virtio-gpu-3d: fix memory leak in resource attach backing
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf8
+Content-Transfer-Encoding: 8bit
+
+If the virgl_renderer_resource_attach_iov function fails the
+'res_iovs' will be leaked. Add check of the return value to
+free the 'res_iovs' when failing.
