Re: [PATCH v8 3/3] tty: 8250_omap: Use software emulated RS485 direction control

[ÐÐÑÑÑ ÐÐÑÐÐÐÐ]

Also, forgot to mention that if serial8250_em485_init is called not
upon uart startup but elsewhere (upon port register for example), and
em485 is set, serial8250_do_startup should call
serial8250_em485_rts_after_send, or else RTS might be in wrong state
whenever the port device is opened, making it impossible to receive
data through RTS-controlled RS232<->RS485 hardware converters.
