[ Upstream commit61170ee938] Commit88ba95bedb("backlight: pwm_bl: Compute brightness of LED linearly to human eye") made the parse-dt function return early when using an auto- generated brightness-table, but didn't take into account that some more settings were handled below the brightness handling, like power-on-delays and also setting the pdata enable-gpio to -EINVAL. This surfaces for example in the case of a backlight without any enable-gpio which then tries to use gpio-0 in error. Fix this by simply moving the trailing settings above the brightness handling.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
