6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miguel Ojeda ojeda@kernel.org
commit c21bdb3d8a850afdfa4afe77eea39ae9533629b0 upstream.
Starting with Rust 1.86.0 (currently in nightly, to be released on 2025-04-03), the `missing_abi` lint is warn-by-default [1]:
error: extern declarations without an explicit ABI are deprecated --> rust/doctests_kernel_generated.rs:3158:1 | 3158 | extern { | ^^^^^^ help: explicitly specify the C ABI: `extern "C"` | = note: `-D missing-abi` implied by `-D warnings` = help: to override `-D warnings` add `#[allow(missing_abi)]`
Thus clean it up.
