Sam Ravnborg 24d34617c2 backlight: cr_bllcd: Introduce gpio-backlight semantics
cr_bllcd can turn backlight ON or OFF.

Fix semantitics so they equals what we know from gpio-backlight.

 brightness == 0   => backlight off
 brightness == 1   => backlight on

Use the backlight_get_brightness() helper to simplify the code.

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.
