This converts the internal backlight in the Sony ACX424AKP driver to do it the canonical way: - Assign the panel->backlight during probe. - Let the panel framework handle the backlight. - Make the backlight .set_brightness() turn the backlight off completely if blank. - Fix some dev_err_probe() use cases along the way. Tested on the U8500 HREF520 reference design.

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.
