From e8c5b56fdca7bb3006914f0bf7d09b4d64254172 Mon Sep 17 00:00:00 2001 From: Liang Li Date: Thu, 24 Jan 2013 12:31:27 +0800 Subject: [PATCH] serial: pch_uart: fix sysrq handling for pch_uart When PCH_UART_CONSOLE and SERIAL_CORE_CONSOLE is not set neither, the uart_port will have no 'sysrq' member hence their will need a '#ifdef' in pch_uart.c to handle the case, otherwise we'll see compile error like this: CC [M] drivers/tty/serial/pch_uart.o drivers/tty/serial/pch_uart.c: In function 'pch_uart_hal_read': drivers/tty/serial/pch_uart.c:572:11: error: 'struct uart_port' has no member named 'sysrq' make[4]: *** [drivers/tty/serial/pch_uart.o] Error 1 Reported-by: Randy Dunlap CC: Stephen Rothwell Signed-off-by: Liang Li Acked-by: Randy Dunlap Signed-off-by: Greg Kroah-Hartman --- 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 1ddfc66b1084..7a6c989924b3 100644 --- a/drivers/tty/serial/pch_uart.c +++ b/drivers/tty/serial/pch_uart.c @@ -569,10 +569,12 @@ static int pch_uart_hal_read(struct eg20t_port *priv, unsigned char *buf, if (uart_handle_break(port)) continue; } +#ifdef SUPPORT_SYSRQ if (port->sysrq) { if (uart_handle_sysrq_char(port, rbr)) continue; } +#endif buf[i++] = rbr; } -- 2.20.1
