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 <rdunlap@infradead.org> CC: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Liang Li <liang.li@windriver.com> Acked-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
