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.
