In cli_add_map() the return value of get_refwwid is never used, and refwwid is checked to see if the function returned successfully, so the return value doesn't need to be saved. In resize_map, if setup_map fails, multipathd shouldn't attempt to create the device with resulting params string. It should just fail instead. Found by coverity.
