Clippy in the upcoming Rust 1.83.0 spots a spurious empty line since the
`clippy::empty_line_after_doc_comments` warning is now enabled by default
given it is part of the `suspicious` group [1]:
error: empty line after doc comment

= note: `-D clippy::empty-line-after-doc-comments` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(clippy::empty_line_after_doc_comments)]`
= help: if the empty line is unintentional remove it
Thus remove the empty line.

I added the Fixes and stable tags since it would be nice to keep the 6.12 LTS
Clippy-clean (since that one is the first that supports several Rust compilers).
