[Linux-stable-mirror] Patch "MIPS: AR7: Defer registration of GPIO" has been added to the 4.13-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled MIPS: AR7: Defer registration of GPIO to the 4.13-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: mips-ar7-defer-registration-of-gpio.patch and it can be found in the queue-4.13 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From e6b03ab63b4d270e0249f96536fde632409dc1dc Mon Sep 17 00:00:00 2001 From: Jonas Gorski <jonas.gorski(a)gmail.com> Date: Sun, 29 Oct 2017 16:27:19 +0100 Subject: MIPS: AR7: Defer registration of GPIO From: Jonas Gorski <jonas.gorski(a)gmail.com> commit e6b03ab63b4d270e0249f96536fde632409dc1dc upstream. When called from prom init code, ar7_gpio_init() will fail as it will call gpiochip_add() which relies on a working kmalloc() to alloc the gpio_desc array and kmalloc is not useable yet at prom init time. Move ar7_gpio_init() to ar7_register_devices() (a device_initcall) where kmalloc works.
