Subject: [PATCH 0/2] rust: sync: Arc: Any downcasting and assume_init()

Hi everyone,

This short series is part of the set of dependencies for the drm/asahi
Apple M1/M2 GPU driver.

The two patches simply add two missing features to the kernel Arc
implementation which are present in the Rust std version: `Any`
downcasting and `assume_init()`.

      rust: sync: arc: implement Arc<dyn Any + Send + Sync>::downcast()
      rust: sync: arc: Add UniqueArc<MaybeUninit<T>::assume_init()
