            Bug ID: 98997
           Summary: Invalid ioctl during Xorg startup
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: reptm-O5WfVfzUwx8@public.gmane.org
        QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org

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.
