This commit adds the same functionality to the rust kernel. Do not merge this commit, because rust/kernel/types.rs in Rust-for-Linux already contains this functionality and will be merged into next-net soon. But this driver does not compile without this commit, so I am adding it to the patchset to get more feedback on the actual driver.
