[PATCH 1/2] drm/vmwgfx: Fix uninitialized return in vmw_cotable_unbind()

From: Christian Engelmayer
Date: Fri Sep 18 2015 - 18:32:33 EST


Function vmw_cotable_unbind() uses the uninitialized variable ret as
return value. Make the result deterministic and directly return as
the variable is unused anyway. Detected by Coverity CID 1324256.
