[PATCH] tty/serial: fix serial_core.c kernel-doc warnings

[Randy Dunlap <rdunlap@xxxxxxxxxxxxx>]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Fix kernel-doc warnings in serial_core.c:

../drivers/tty/serial/serial_core.c:3300: warning: Function parameter or member 'port' not described in 'uart_get_rs485_mode'
../drivers/tty/serial/serial_core.c:3300: warning: Excess function parameter 'dev' description in 'uart_get_rs485_mode'
../drivers/tty/serial/serial_core.c:3300: warning: Excess function parameter 'rs485conf' description in 'uart_get_rs485_mode'

Fixes: c150c0f362c1 ("serial: Allow uart_get_rs485_mode() to return errno")
