[PATCH v3 0/2] drm: Store USB device in struct drm_device

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)

Thomas Zimmermann (2):
  drm/tiny/gm12u320: Retrieve USB device from struct drm_device.dev
  drm/udl: Retrieve USB device from struct drm_device.dev
