    - DRM IOCTL
    - DRM File
    - GEM object
  - IntoGEMObject rework
    - generically implement AlwaysRefCounted through IntoGEMObject
    - refactor unsound from_gem_obj() into as_ref()
    - refactor into_gem_obj() into as_raw()

driver-core:

  - implement Devres::access()
    - fix: doctest build under `!CONFIG_PCI`
  - accessor for Device::parent()
    - fix: conditionally expect `dead_code` for `parent()`
  - impl TryFrom<&Device> bus devices (PCI, platform)

nova-core:
  - remove completed Vec extentions from task list
  - register auxiliary device for nova-drm
  - derive useful traits for Chipset
  - add missing GA100 chipset
  - take &Device<Bound> in Gpu::new()

nova-drm:
  - initial driver skeleton (depends on drm and auxiliary bus
    abstractions)
