Now the xserver MR is at https://gitlab.freedesktop.org/xorg/xserver/merge_requests/335
with explaining the same as I wrote in the previous mail in the commit message.

I have also created https://gitlab.freedesktop.org/xorg/xserver/merge_requests/336
to fix the same issue when using BusID for the UDL device.

Best regards,
