In the Linux kernel, the following vulnerability has been resolved:
serial: arc_uart: fix of_iomap leak in `arc_serial_probe`
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.
