From ab90151162d39607e264e715a582e783e0da3c3a Mon Sep 17 00:00:00 2001
From: Peter Hutterer <peter.hutterer@who-t.net>
Date: Tue, 18 Jan 2011 12:55:46 +1000
Subject: Add --name-only flag for 'xinput list'.

The default output of xinput list is hard to parse by scripts. Provide a
--name-only option to print the device name only, without any other
information.
