rust/kernel: Add faux device bindings This introduces a module for working with faux devices in rust, along with adding sample code to show how the API is used. Unlike other types of devices, we don't provide any hooks for device probe/removal - since these are optional for the faux API and are unnecessary in rust.

rust: module: introduce `authors` key In the `module!` macro, the `author` field is currently of type `String`. Since modules can have multiple authors, this limitation prevents specifying more than one. Add an `authors` field as `Option<Vec<String>>` to allow creating modules with multiple authors, and change the documentation and all current users to use it. Eventually, the single `author` field may be removed. [ The `modinfo` key needs to still be `author`; otherwise, tooling may not work properly, e.g.: $ modinfo --author samples/rust/rust_print.ko Rust for Linux Contributors I have also kept the original `author` field (undocumented), so that we can drop it more easily in a kernel cycle or two. - Miguel ] Suggested-by: Miguel Ojeda <ojeda@kernel.org> Link: https://github.com/Rust-for-Linux/linux/issues/244 Reviewed-by: Charalampos Mitrodimas <charmitro@posteo.net> Reviewed-by: Alice Ryhl <aliceryhl@google.com> Reviewed-by: Andreas Hindborg <a.hindborg@kernel.org> Signed-off-by: Guilherme Giacomo Simoes <trintaeoitogc@gmail.com> Link: https://lore.kernel.org/r/20250309175712.845622-2-trintaeoitogc@gmail.com [ Fixed `modinfo` key.
