Indeed, I had the PR linked in
https://github.com/Rust-for-Linux/linux/issues/349, and it is nicer,
but it would still fire in a case like this patch :(

So we could conditionally enable it for Rust >= 1.90.0 now that we
have support for that (and allow locally some cases like this one when
they pop up), but it is still simpler to just ignore it (especially
since it can be quite confusing for other developers to see it
triggering).

I think we may want to eventually re-enable it when we use no unstable
language features.

Added:

    [ In addition, the lint fired without taking into account the features
      that have been enabled in a crate [2]. While this was improved in Rust
      1.90.0 [3], it would still fire in a case like this patch. ]

Thanks!

Cheers,
Miguel
