From 808f74da665bb932664b4950fe86e05910c77537 Mon Sep 17 00:00:00 2001
From: Dorian Stoll <dorian.stoll@tmsp.io>
Date: Sat, 27 Jun 2020 18:21:11 +0200
Subject: [PATCH 01/16] Add support for BUS_VIRTUAL
This is needed to support IPTS devices through the iptsd userspace
daemon. It exposes the touchscreen / stylus as uinput, since the parsing
of raw IPTS data needs to happen in userspace.
Because these devices are not backed by an actual bus, they are created
as BUS_VIRTUAL.
