Some GPIO lines have stopped working after the patch commit2ab73c6d83("gpio: Support GPIO controllers without pin-ranges") And this has supposedly been fixed in the following patches commit89ad556b7f("gpio: Avoid using pin ranges with !PINCTRL") commit6dbbf84603("gpiolib: Don't free if pin ranges are not defined") But an erratic behavior where some GPIO lines work while others do not work has been introduced. This patch reverts those changes so that the sysfs-gpio interface works properly again.

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.
