From ee5cb7c465360f8eabc351196554e534675bdf6b Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 14 Mar 2017 10:54:10 +0300 Subject: [PATCH] drm: qxl: add missing return check My static checker complains that "release" is uninitialized if qxl_alloc_release_reserved() fails, so let's add a check for that.
