[PATCH 6/9] serial-uartlite: Change logic how console_port is setup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Shubhrajyoti Datta <shubhrajyoti.datta@xxxxxxxxxx>

Change logic how console_port is setup by using CON_ENABLED flag
instead of index. There will be unique uart_console
structure that's why code can't use id for console_port
assignment.
