mailbox: mailbox-test: avoid reading iomem twice
Don't pass mmio region as source to print_hex_dump() and then again to memcpy_fromio(). Do it once and give print_hex_dump() the buffer we just read the data in. Acked-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
