From 384fa8647dc55ab47515bbb76ebda37b2350e5b3 Mon Sep 17 00:00:00 2001 From: Lino Sanfilippo Date: Sun, 7 Apr 2024 02:27:08 +0200 Subject: [PATCH] serial: 8250: Remove superfluous sanity check The serial core already checks the RS485 RTS settings for sanity, so remove the superfluous check in serial8250_em485_config().
