Function wait_for_xmitr is invoked only on functions that either depend on CONFIG_CONSOLE_POLL or CONFIG_SERIAL_PCH_UART_CONSOLE. This patch fixes the following warning: drivers/tty/serial/pch_uart.c:1504:13: warning: ‘wait_for_xmitr’ defined but not used [-Wunused-function] Signed-off-by: Luis Henriques <luis.henriques@xxxxxxxxxxxxx> --- drivers/tty/serial/pch_uart.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/tty/serial/pch_uart.c b/drivers/tty/serial/pch_uart.c index 572d481..1e22a49 100644 --- a/drivers/tty/serial/pch_uart.c +++ b/drivers/tty/serial/pch_uart.c @@ -1498,6 +1498,7 @@ static int pch_uart_verify_port(struct uart_port *port, return 0; } +#if defined(CONFIG_CONSOLE_POLL) || defined(CONFIG_SERIAL_PCH_UART_CONSOLE) /* * Wait for transmitter & holding register to empty */ @@ -1528,6 +1529,7 @@ static void wait_for_xmitr(struct eg20t_port *up, int bits) } } } +#endif /* CONFIG_CONSOLE_POLL || CONFIG_SERIAL_PCH_UART_CONSOLE */ #ifdef CONFIG_CONSOLE_POLL /* -- 1.8.3.2 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
