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
