Remove the code to unregister acpi_video backlight devices when a native backlight device gets registered later. Now that the acpi_video backlight device registration is a separate step which runs later, after the drm/kms driver is done setting up its own native backlight device, it is no longer necessary to monitor for a native (BACKLIGHT_RAW) device showing up later and to then unregister the acpi_video backlight device(s).

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.
