Have you checked that this still works with DT properties on a USB device
that is listed in the DT? A common use-case is to provide the MAC address
of a soldered-down USB-ethernet that lacks its own eeprom, and it seems
you are changing the way the parent devices of that get represented,
so the dev->of_node pointer in the USB device might no longer refer
to the correct device.
