Subject: [PATCH 0/3] rust: WMI abstractions

Overview
========
This patchset implements WMI abstractions for Rust drivers. It is the successor
of the previous RFC posting [0]. These abstractions allow most WMI drivers to be
implemented in Rust (provided other dependencies are abstracted as well).

Currently, the only driver in existence is a stripped-down rewrite of redmi-wmi
that can probe itself with custom data and print messages on notification
(posted in [0]).

I am currently working on wrapping redmi-wmi's other dependencies (sparse-keyboard),
so I can provide it as a reference driver (Armin is OK with that [1]).

Notes
=====
I do not know how these abstractions should be handled in MAINTAINERS, so for now I have
simply added them to the original WMI entry. I would be happy to be added as a reviewer
to keep the Rust version 'synced'/valid though.
