Subject: [PATCH v9 0/2] modularize Rust lints and add RUST_UNWRAP check

This series moves Rust-specific linting logic into a separate file to
prevent further growth of the main scripts/checkpatch.pl script and
introduces a new lint to enforce safety standards.

The first patch creates the infrastructure for scripts/rust_checkpatch.pl
and adds a conditional loading hook in the main checkpatch script. It
also updates the MAINTAINERS file to track this new file.

The second patch introduces the  RUST_UNWRAP lint, which warns against
the use of .unwrap() and .expect() unless they are accompanied by a 
'// PANIC:' justification comment.

Jason Hall (2):
  scripts: checkpatch: move Rust-specific lints to separate file
  scripts: checkpatch: add RUST_UNWRAP lint
