net/irda: sh_sir: Modify iounmap wrong execution
On sh_sir_probe function, there was a possibility that iounmap is executed even though self->membase was NULL when error case. This patch modify it. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: David S. Miller <davem@davemloft.net>
