Merge tag 'pin-init-v6.17' of https://github.com/Rust-for-Linux/linux into rust-next

Pull pin-init updates from Benno Lossin:
 "Added:

   - 'impl<T, E> [Pin]Init<T, E> for Result<T, E>', so results are now
     (pin-)initializers.

   - 'Zeroable::init_zeroed()' delegating to 'init_zeroed()'.

   - New 'zeroed()', a safe version of 'mem::zeroed()' and also provide
     it via 'Zeroable::zeroed()'.

   - Implement 'Zeroable' for 'Option<&T>' and 'Option<&mut T>'.

   - Implement 'Zeroable' for 'Option<[unsafe] [extern "abi"]
     fn(...args...) -> ret>' for '"Rust"' and '"C"' ABIs and up to 20
     arguments.

  Changed:

   - Blanket impls of 'Init' and 'PinInit' from 'impl<T, E>
     [Pin]Init<T, E> for T' to 'impl<T> [Pin]Init<T> for T'.

   - Renamed 'zeroed()' to 'init_zeroed()'.

  Upstream dev news:

   - More CI improvements to deny warnings, use '--all-targets'. Also
     check the synchronization status of the two '-next' branches in
     upstream and the kernel."
