serial: 8250: omap: Use serial8250_em485_supported
Browse files Browse the repository at this point in the history
8250_omap uses em485, fill in rs485_supported accordingly. This makes
RS485 work with 8250_omap again, which was broken with the introduction
of the RS485 config sanitization.

Fixes: be2e2cb ("serial: Sanitize rs485_struct")
