If anyone has any objections, please let me know. ------------------ From: Johannes Berg [ Upstream commit 75fd4fec3e4c43b131c7c4958adb3ab9f1665513 ] The earlier patch called the station add functions but didn't assign their return value to the ret variable, so that the checks for it were meaningless. Fix that.
