[PATCH v9 16/27] scripts: checkpatch: enable language-independent checks for Rust

Miguel Ojeda
2022-08-05T15:47:52Z

Include Rust in the "source code files" category, so that
the language-independent tests are checked for Rust too,
and teach `checkpatch` about the comment style for Rust files.

This enables the malformed SPDX check, the misplaced SPDX license
tag check, the long line checks, the lines without a newline check
and the embedded filename check.
