[PATCH 6/9] serial: max310: remove redundant code in rs485_config

From: Lino Sanfilippo
Date: Sun Feb 13 2022 - 17:34:16 EST


When RS485 is configured by userspace the serial core already nullifies the
padding field of the returned configuration struct. Doing the same in the
drivers rs485_config function is redundant, so remove the concerning
code in this function.
