[ Upstream commit fc328a7d1fcce263db0b046917a66f3aa6e68719 ]
Some GPIO lines have stopped working after the patch commit 2ab73c6d8323f ("gpio: Support GPIO controllers without pin-ranges")
And this has supposedly been fixed in the following patches commit 89ad556b7f96a ("gpio: Avoid using pin ranges with !PINCTRL") commit 6dbbf84603961 ("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.

I think you should not apply this for stable, because we will revert the revert.
