From 7dd9cd29a6cb0f075f7face47f8a0629bf13f0c6 Mon Sep 17 00:00:00 2001 From: Olivier Fourdan Date: Wed, 11 Mar 2020 15:03:03 +0100 Subject: input: Avoid creating the PAD device multiple times If a pad device for a tablet exists, reloading the configuration, removing/reading the device or even suspending the system will recreate the same Wayland input device multiple times. Make sure we don't re-create the same Wayland device more than necessary.
