The drivers gm12u320 and udl operate on USB devices. They leave the PCI device in struct drm_device empty and store the USB device in their own driver structure. It's expected that DRM core and helpers only touch the PCI-device field for actual PCI devices.
Fix this special case by upcasting struct drm_device.dev to the USB device. The drivers' udev variables are being removed.
v3: * drop USB helper in favor of driver-internal helpers (Daniel) v2: * upcast USB device from struct drm_device.dev (Daniel)
