[PATCH 0/3] drm: Store USB device in struct drm_device

[Thomas Zimmermann]

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.

Fix this special case and save a few bytes by putting the USB device
into an anonymous union with the PCI data. It's expected that DRM
core and helpers only touch the PCI-device field for actual PCI devices.

Thomas Zimmermann (3):
  drm: Add reference to USB device to struct drm_device
  drm/tiny/gm12u320: Store USB device in struct drm_device.udev
  drm/udl: Store USB device in struct drm_device.udev
