Date: Sat, 16 May 2015 09:37:55 +0200 From: Jiri Slaby <jslaby@...e.cz> To: stable@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Johan Hovold <johan@...nel.org>, Linus Walleij <linus.walleij@...aro.org>, Jiri Slaby <jslaby@...e.cz> Subject: [PATCH 3.12 115/142] gpio: unregister gpiochip device before removing it From: Johan Hovold <johan@...nel.org> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 01cca93a9491ed95992523ff7e79dd9bfcdea8e0 upstream. Unregister gpiochip device (used to export information through sysfs) before removing it internally. This way removal will reverse addition.
