serial: doc: Always refer to tty_port->mutex
Stop referring to the mutex member of the tty_port struct as 'port->mutex', as 'port' is ambiguous, and usually refers to the uart_port struct in this document. Use 'tty_port->mutex' instead, following the single existing use. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
