(to avoid code duplication) We really want to handle it at the tty layer I think not at serial_core. I have a patch for that and I'm playing with it but it's taking longer than I hoped. In the mean time I think your patch #1 is ok except for the trivial item that I'd prefer the struct serial_rs485 was further down the struct uart_8250_port. It's packed so that the bits you need most are in the first cache line or two.
