If it's really necessary to use 80 columns,
I'd prefer this sort of change be:
serial_outp(up, UART_RSA_MSR,
mode & ~UART_RSA_MSR_FIFO);

I think it's better to have all the or's
on the same line where possible.
serial_outp(up, UART_FCTR,
fctr | UART_FCTR_TRGD | UART_FCTR_RX);

It might be better to use
static struct uart_8250_port *
serial8250_find_match_or_unused(struct uart_port *port)

Broken.
Don't use line continuations with whitespace on the next line.
Better not use line continations at all except in #defines

Useless line continuation.
