of_gpiochip_add(), when fails, calls gpiochip_remove_pin_ranges().
ADD:
gpiochip_add_data_with_key() ->
of_gpiochip_add() -> (ERROR path)
gpiochip_remove_pin_ranges()
At the same time of_gpiochip_remove() calls exactly the above mentioned
function unconditionally and so does gpiochip_remove().
REMOVE:
gpiochip_remove() ->
gpiochip_remove_pin_ranges()
of_gpiochip_remove() ->
gpiochip_remove_pin_ranges()
Since gpiochip_remove() calls gpiochip_remove_pin_ranges() unconditionally,
we have duplicate call to the same function when it's not necessary.
Move gpiochip_remove_pin_ranges() from of_gpiochip_add() to gpiochip_add()
to avoid duplicate calls and be consistent with the explicit call in
gpiochip_remove().
Fixes: e93fa3f243 ("gpiolib: remove duplicate pin range code")
Depends-on: f7299d441a ("gpio: of: Fix of_gpiochip_add() error path")

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.
