Refactor register_backlight_device(): 1) Turn the connector-type + signal check into an early exit condition to avoid the indentation level of the rest of the code 2) Add an array bounds check for the arrays indexed by dm->num_of_edps 3) register_backlight_device() always increases dm->num_of_edps if amdgpu_dm_register_backlight_device() has assigned a backlight_dev to the current dm->backlight_link[dm->num_of_edps] slot. So on its next call dm->backlight_dev[dm->num_of_edps] always point to the next empty slot and the "if (!dm->backlight_dev[dm->num_of_edps])" check will thus always succeed and can be removed. 4) Add a bl_idx local variable to use as array index, rather then using dm->num_of_edps to improve the code readability.

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.
