mailbox: imx: Fix return in imx_mu_scu_xlate()
This called from mbox_request_channel(). The caller is expecting error pointers and not NULL so this "return NULL;" will lead to an Oops. Fixes: 0a67003b1985 ("mailbox: imx: add SCU MU support") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
