linux-next: build failure after merge of the final tree (pinctrltree related)

Hi all,

After merging the final tree, today's linux-next build (powerpc
ppc44x_defconfig) failed like this:

In file included from include/linux/gpio.h:48:0,
from include/linux/of_gpio.h:20,
from arch/powerpc/sysdev/ppc4xx_gpio.c:29:
include/asm-generic/gpio.h:74:10: error: 'struct gpio_chip' declared inside parameter list [-Werror]
include/asm-generic/gpio.h:74:10: error: its scope is only this definition or declaration, which is probably not what you want [-Werror]
include/asm-generic/gpio.h: In function 'gpiochip_add_pin_range':
include/asm-generic/gpio.h:76:1: error: no return statement in function returning non-void [-Werror=return-type]
include/asm-generic/gpio.h: At top level:
include/asm-generic/gpio.h:79:35: error: 'struct gpio_chip' declared inside parameter list [-Werror]

Caused by commit e8321df59155 ("gpiolib: iron out include ladder
mistakes") (and some earlier ones) from the pinctrl tree.

I added this patch for today (there may be a better return value from
gpiochip_add_pin_range):
