Ke Zhang f76a18e53a serial: arc_uart: fix of_iomap leak in arc_serial_probe
[ Upstream commit 8ab5fc55d7 ]

Smatch reports:

drivers/tty/serial/arc_uart.c:631 arc_serial_probe() warn:
'port->membase' from of_iomap() not released on lines: 631.

In arc_serial_probe(), if uart_add_one_port() fails,
port->membase is not released, which would cause a resource leak.

To fix this, I replace of_iomap with devm_platform_ioremap_resource.

Fixes: 8dbe1d5e09 ("serial/arc: inline the probe helper")
