+Subject: drm/edid: Fix uninitialized variable in drm_cvt_modes()
+
+From: Lyude Paul <lyude@redhat.com>
+
+commit 991fcb77f490390bcad89fa67d95763c58cdc04c upstream.
+
+Noticed this when trying to compile with -Wall on a kernel fork. We
+potentially don't set width here, which causes the compiler to complain
+about width potentially being uninitialized in drm_cvt_modes(). So, let's
+fix that.
+
+Changes since v1:
+* Don't emit an error as this code isn't reachable, just mark it as such
+Changes since v2:
+* Remove now unused variable
+
+Fixes: 3f649ab728cd ("treewide: Remove uninitialized_var() usage")
