From 0e066b2cc50de4b4d5ef3c9b5a39eddc3f98d060 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Fri, 11 Mar 2016 08:38:20 +0100 Subject: input-linux: switch over to -object This patches makes input-linux use -object instead of a new command line switch. So, instead of the switch ... -input-linux /dev/input/event$nr ... you must create an object this way: -object input-linux,id=$name,evdev=/dev/input/event$nr Bonus is that you can hot-add and hot-remove them via monitor now.
