Without the ampersand.  Also, SvGETMAGIC is not an expression, but a statement, in 5.14 and earlier.  If you want to support perl older than 5.16, you need to make it a separate statement:

T_PV
        SvGETMAGIC($arg);
        $var = SvOK ($arg) ? ($type) SvPV_nomg($arg, PL_na) : NULL;

(A typemap can be multiple statements, right?)
