pasemi_mac: mac_to_intf() error not noticed
mac_to_intf() can return -1 when no device or function is found, but when mac->dma_if is unsigned. The error wasn't noticed. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Acked-by: Olof Johansson <olof@lixom.net> Signed-off-by: David S. Miller <davem@davemloft.net>
