tty/serial/sirf: fix error propagation in sirfsoc_uart_probe()
If pinctrl_get_select_default() fails, sirfsoc_uart_probe() returns IS_ERR(result) instead of PTR_ERR(result). Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov <khoroshilov@ispras.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
