Merge tag 'pin-init-v6.18' of https://github.com/Rust-for-Linux/linux into drm-rust...

pin-init changes for v6.18

Changed:

- `#[pin_data]` now generates a `*Projection` struct similar to the
  `pin-project` crate.

- Add initializer code blocks to `[try_][pin_]init!` macros: make
  initializer macros accept any number of `_: {/* arbitrary code */},` &
  make them run the code at that point.

- Make the `[try_][pin_]init!` macros expose initialized fields via a
  `let` binding as `&mut T` or `Pin<&mut T>` for later fields.

Upstream dev news:

- Released v0.0.10 before the changes included in this tag.

- Inform users of the impending rename from `pinned-init` to `pin-init`
  (in the kernel the rename already happened).

- More CI improvements.
