Jian-Hong Pan 3e4008fbdf platform/x86: asus-wmi: Fix keyboard brightness cannot be set to 0
commit 176a7fca81c5090a7240664e3002c106d296bf31 upstream.

Some of ASUS laptops like UX431FL keyboard backlight cannot be set to
brightness 0. According to ASUS' information, the brightness should be
0x80 ~ 0x83. This patch fixes it by following the logic.

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.
