Description Tad 2016-12-05 12:20:46 UTC

OS:    Ubuntu 16.10
Kernel: 4.8.0-28-generic
xorg-server: 1.18.4
cpu: Intel(R) Core(TM) i7-3720QM CPU @ 2.60GHz


After connecting UDL device and restarting Xorg, Xorg tries to send invalid ioctl to that device.

Looks like Xorg enumerates existing drm devices and performs driver's platformprobe function on them regardless of their type.
