This is a well-structured v6 series introducing a `DeviceContext` typestate pattern for the Rust DRM device bindings, allowing compile-time enforcement of device initialization stages. The design is sound: it cleanly separates `Uninit` (possibly uninitialized/unregistered) from `Registered` (known to have been registered), and uses `UnregisteredDevice` as a non-thread-safe newtype to represent a device that is guaranteed to be pre-registration.
The series fixes a real bug (patch 1), introduces the core typestate mechanism (patch 2), defers driver data initialization to registration time (patch 3), adds a convenience type alias (patch 4), and propagates DeviceContext through GEM objects (patch 5). The progression is logical and each patch is well-motivated.
A few concerns are noted per-patch below, primarily around memory ordering, error handling in patch 3, and the soundness of `assume_ctx`'s transmute.
