This driver adds support for missing hotkeys on some Huawei laptops. Laptops such as the Matebook X have non functioning hotkeys. Whereas newer laptops such as the Matebook X Pro come with working hotkeys out of the box. Old laptops, such as the Matebook X, report hotkey events through ACPI device "\WMI0". However, new laptops, such as the Matebook X Pro, does not have this WMI device. All the hotkeys on the Matebook X Pro work fine without this patch except (micmute, wlan, and huawei key). These keys and the brightness keys report events to "\AMW0" ACPI device. One problem is that brightness keys on the Matebook X Pro work without this patch. This results in reporting two brightness key press events one is captured by ACPI and another by this driver. A solution would be to check if such event came from the "\AMW0" WMI driver then skip reporting event. Another solution would be to leave this to user-space to handle. Which can be achieved by using "hwdb" tables and remap those keys to "unknown". This solution seems more natural to me because it leaves the decision to user-space.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
