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`. It is unsafe to create this 19 | | /// type, since the closure needs to fulfill the same safety requirement as the 20 | | /// `__pinned_init`/`__init` functions. | |_ | = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#too_long_first_doc... = note: `-D clippy::too-long-first-doc-paragraph` implied by `-D warnings` = help: to override `-D warnings` add `#[allow(clippy::too_long_first_doc_paragraph)]`
error: first doc comment paragraph is too long --> rust/kernel/sync/arc/std_vendor.rs:3:1 | 3 | / //!

Thus clean those two instances.
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)`).
