commit f0915acd1fc6060a35e3f18673072671583ff0be upstream.
Clippy's lints may avoid emitting a suggestion to use a language or library feature that is not supported by the minimum supported version, if given by the `msrv` field in the configuration file.
For instance, Clippy should not suggest using `let ... else` in a lint if the MSRV did not implement that syntax.
If the MSRV is not provided, Clippy will assume all features are available.
Thus enable it with the minimum Rust version the kernel supports.
Note that there is currently a small disadvantage in doing so: since we still use unstable features that nevertheless work in the range of versions we support (e.g. `#[expect(...)]`), we lose suggestions for those. However, over time we will stop using unstable features (especially language and library ones) as it is our goal, thus, in the end, we will want to have the `msrv` set.
Rust is also considering adding a similar feature in `rustc` too, which we should probably enable if it becomes available [2].
