Hans de Goede 420a1116ae ACPI: video: Allow selecting NVidia-WMI-EC or Apple GMUX backlight from the cmdline
The patches adding NVidia-WMI-EC and Apple GMUX backlight detection
support to acpi_video_get_backlight_type(), forgot to update
acpi_video_parse_cmdline() to allow manually selecting these from
the commandline.

Add support for these to acpi_video_parse_cmdline().

Fixes: fe7aebb40d ("ACPI: video: Add Nvidia WMI EC brightness control detection (v3)")
Fixes: 21245df307 ("ACPI: video: Add Apple GMUX brightness control detection")

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.
