[PATCH 9/9] serial: atmel: remove redundant assignment in rs485_config

From: Lino Sanfilippo
Date: Sun Feb 13 2022 - 17:33:53 EST


When RS485 is configured by userspace the serial core already assigns the
passed configuration to the uart port. So remove the assignment from the
drivers rs485_config function to avoid redundancy.
