       CID 318094:  Null pointer dereferences  (REVERSE_INULL)
       Null-checking "version" suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
    1389     	if (version == NULL) {
    1390     		return (result);
    1391     	}
    1392
    1393     	*versionp = version;
