Merge tag 'rust-fixes-6.3' of https://github.com/Rust-for-Linux/linux

Pull Rust fixes from Miguel Ojeda:
 "Most of these are straightforward.

  The last one is more complex, but it only touches Rust + GCC builds
  which are for the moment best-effort.

   - Code: Missing 'extern "C"' fix.

   - Scripts: 'is_rust_module.sh' and 'generate_rust_analyzer.py' fixes.

   - A couple trivial fixes

   - Build: Rust + GCC build fix and 'grep' warning fix"
