From 46b94e779e8a53b83e8d84e5aeb443d8b8bd45ea Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Sun, 10 Jan 2016 22:40:51 -0800 Subject: [PATCH] serial: 68328: Remove bogus ldisc reset As the #warning indicates, the open-coded ldisc reset was always not ok. Not only is this code long dead, but now it would have no effect as the ldisc is destroyed when this driver's close() method returns; remove.
