From 5813f281bba6603bed52d6005a9d6a9f23f5c061 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 21 Mar 2013 12:37:40 +0100 Subject: [PATCH] USB: metro-usb: always disable uart on close Always try to disable the uart on close. Since the switch to tty ports, close will be called as part of shutdown before disconnect returns. Hence there is no need to check the disconnected flag, and we can put devices in disabled states also on driver unbind.
