commitb21a142fd2upstream. Currently we can get a warning on systems with eDP backlights like so: nv_backlight: invalid backlight type WARNING: CPU: 4 PID: 454 at drivers/video/backlight/backlight.c:420 backlight_device_register+0x226/0x250 This happens as a result of us not filling out props.type for the eDP backlight, even though we do it for all other backlight types. Since nothing in our driver uses anything but BACKLIGHT_RAW, let's take the props\.type assignments out of the codepaths for individual backlight types and just set it unconditionally to prevent this from happening again.

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.
