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 --> drivers/gpu/drm/drm_panic_qr.rs:931:1 | 931 | / /// They must remain valid for the duration of the function call. 932 | | | |_ 933 | #[no_mangle] 934 | / pub unsafe extern "C" fn drm_panic_qr_generate( 935 | | url: *const i8, 936 | | data: *mut u8, 937 | | data_len: usize, ... | 940 | | tmp_size: usize, 941 | | ) -> u8 { | |_______- the comment documents this function | = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#empty_line_after_d... = 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.
Cc: stable@vger.kernel.org Fixes: cb5164ac43d0 ("drm/panic: Add a QR code panic screen") Link: https://github.com/rust-lang/rust-clippy/pull/13091 [1] Signed-off-by: Miguel Ojeda ojeda@kernel.org --- 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).
