Solve the following python programming problem given the following code:
def dot_2_mv(context, builder, sig, args) : 
    '
    np.dot(matrix, vector)
    ' 
    def dot_impl(a, b) : 
        (m, n) = a.shape 
        (_n,) = b.shape 
        out = numpy.empty ((m,), a.dtype) 
        return numpy.dot (a, b, out) 
res = context.compile_internal (builder, dot_impl, sig, args) 
    return impl_ret_new_ref (context, builder, builder.return_type, res) 

    
    

    Fix the buggy line: return impl_ret_new_ref (context, builder, builder.return_type, res)
