Subject: [PATCH] serial: ar933x_uart: Fix build failure with disabled console

Andrey has reported on OpenWrt's bug tracking system[1], that he
|
||
|
|
currently can't use ar93xx_uart as pure serial UART without console
|
||
|
|
(CONFIG_SERIAL_8250_CONSOLE and CONFIG_SERIAL_AR933X_CONSOLE undefined),
|
||
|
|
because compilation ends with following error:
|
||
|
|
|
||
|
|
ar933x_uart.c: In function 'ar933x_uart_console_write':
|
||
|
|
ar933x_uart.c:550:14: error: 'struct uart_port' has no
|
||
|
|
member named 'sysrq'
|
||
|
|
|
||
|
|
So this patch moves all the code related to console handling behind
|
||
|
|
series of CONFIG_SERIAL_AR933X_CONSOLE ifdefs.
