From b1096cc5914d26ce32836876aa939a02e47d7c03 Mon Sep 17 00:00:00 2001 From: Lino Sanfilippo Date: Sun, 10 Apr 2022 12:46:39 +0200 Subject: [PATCH] serial: max310: remove redundant memset in rs485_config In uart_set_rs485_config() the serial core already nullifies the padding field of the passed serial_rs485 struct before returning it to userspace. Doing the same in the drivers rs485_config() function is redundant, so remove the concerning memset in this function.
