From 864c329b21a1914105a9e591b49def3f30184b65 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 12 Jan 2015 17:12:29 +0100 Subject: gpio: unregister gpiochip device before removing it commit 01cca93a9491ed95992523ff7e79dd9bfcdea8e0 upstream. Unregister gpiochip device (used to export information through sysfs) before removing it internally. This way removal will reverse addition.
