Why not set it in > drivers/tty/serial/of_serial.c? I imagine the code could go in either place. I don't see any advantage moving it to of_serial.c, and it'd actively be a disadvantage as far as I'm concerned; PORT_TEGRA is defined in 8250.c, and other code which enable the same UART_BUG_NOMSR flag is in exactly the same place, which keeps similar code co-located. -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
