commit 2f390cc589433dfcfedc307a141e103929a6fd4d upstream. Rust 1.82.0's Clippy is introducing [1][2] a new warn-by-default lint, `too_long_first_doc_paragraph` [3], which is intended to catch titles of code documentation items that are too long (likely because no title was provided and the item documentation starts with a paragraph). This lint does not currently trigger anywhere, but it does detect a couple cases if checking for private items gets enabled (which we will do in the next commit): error: first doc comment paragraph is too long --> rust/kernel/init/__internal.rs:18:1 | 18 | / /// This is the module-internal type implementing `PinInit` and `Init`.

In addition, since we have a second `std_vendor.rs` file with a similar header, do the same there too (even if that one does not trigger the lint, because it is `doc(hidden)`).
