Marcelo Roberto Jimenez a4f4ce3dee gpio: Revert regression in sysfs-gpio (gpiolib.c)
[ Upstream commit fc328a7d1fcce263db0b046917a66f3aa6e68719 ]

Some GPIO lines have stopped working after the patch
commit 2ab73c6d83 ("gpio: Support GPIO controllers without pin-ranges")

And this has supposedly been fixed in the following patches
commit 89ad556b7f ("gpio: Avoid using pin ranges with !PINCTRL")
commit 6dbbf84603 ("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.
