rust: drm: pin ioctl Device reference to Normal context

Browse source

Explicitly annotate the Device reference produced by from_raw() in the
ioctl dispatch macro as Device<_, Normal>. Without this annotation, the
context is inferred from the handler's first parameter type, which would
allow a handler declaring &Device<T, Registered> to obtain a Registered
reference without runtime proof via RegistrationGuard.
