From 6d9beff6ce231527dfd59e896c6cf3730555121a Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 13 Sep 2012 18:44:06 +1000 Subject: [PATCH] config/udev: ignore change on drm devices for input devices we handle change like remove/add, but for drm devices we get change events when we hotplug outputs, so lets just ignore change at this level, and let the drivers handle it. We may in the future want to route driver udev from here instead.
