On Apple laptops with an Apple GMUX using this for brightness control, should take precedence of any other brightness control methods. Add apple-gmux detection to acpi_video_get_backlight_type() using the already existing apple_gmux_present() helper function. This will allow removig the (ab)use of: acpi_video_set_dmi_backlight_type(acpi_backlight_vendor); Inside the apple-gmux driver. Acked-by: Rafael J.

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.
