gpio: Revert regression in sysfs-gpio (gpiolib.c)
Some GPIO lines have stopped working after the patch commit 2ab73c6d ("gpio: Support GPIO controllers without pin-ranges") And this has supposedly been fixed in the following patches commit 89ad556b ("gpio: Avoid using pin ranges with !PINCTRL") commit 6dbbf846 ("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.
