Merge tag 'pin-init-v7.0' of https://github.com/Rust-for-Linux/linux into rust-next

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

   - Implement 'InPlaceWrite' for '&'static mut MaybeUninit<T>'. This
     enables users to use external allocation mechanisms such as
     'static_cell'.

   - Add Gary Guo as a Maintainer.

  Changed:

   - Rewrote all proc-macros ('[pin_]init!', '#[pin_data]',
     '#[pinned_drop]', 'derive([Maybe]Zeroable)'), using 'syn' with
     better diagnostics.

   - Support tuple structs in 'derive([Maybe]Zeroable)'.

   - Support attributes on fields in '[pin_]init!' (such as
     '#[cfg(...)]').

   - Add a '#[default_error(<type>)]' attribute to '[pin_]init!' to
     override the default error (when no '? Error' is specified).

   - Support packed structs in '[pin_]init!' with
     '#[disable_initialized_field_access]'.

  Removed:

   - Remove 'try_[pin_]init!' in favor of merging their feature
     with '[pin_]init!'. Update the kernel's own 'try_[pin_]init!'
     macros to use the 'default_error' attribute.

  Fixed:

   - Correct 'T: Sized' bounds to 'T: ?Sized' in the generated
     'PinnedDrop' check by '#[pin_data]'."
