Subject: [PATCH] Avoid crash if querying device that has gone away
A device removed very fast after being inserted might disappear while
we are still seting it up. We must therefore check if we indeed still
get a matching device

From 19d289ab1b5bde3e136765e5432b5c7d004df3a4 Mon Sep 17 00:00:00 2001
From: Maarten Lankhorst <maarten.lankhorst@canonical.com>
Date: Tue, 20 May 2014 09:57:39 +0200
Subject: [PATCH] Listen to touch events on the master device instead of slave.
Listening to touch events on the master prevents pointer emulation
events from being generated, alleviating the need to grab.
Grabbing on the slave device is buggy, and breaks pointer emulation
on all current servers that support XInput 2.2 due to a bug in the
server, and will also grab unwanted touch events.
For reference, see https://bugs.freedesktop.org/show_bug.cgi?id=78345
Reverts 2c65b78b400ec27e6e559829b9a970dca2df6669. The idea of
enabling each touchscreen separately was introduced in
4dbf574b7acb7ae8f852219700afa95f8d568f0e; that aspect is also
reverted.
