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

Hi all,

After merging the final tree, today's linux-next build (sparc32 defconfig)
failed like this:

In file included from drivers/spi/spi.c:33:0:
include/linux/of_gpio.h: In function 'of_get_named_gpio_flags':
include/linux/of_gpio.h:93:3: error: implicit declaration of function 'desc_to_gpio' [-Werror=implicit-function-declaration]

Caused by commit af8b6375a829 ("gpiolib: port of_ functions to use
gpiod") from the gpio tree.

I have applied the following patch for today (it should go into the gpio
tree if it is considered correct):

Subject: [PATCH] gpiolib: include gpio/consumer.h in of_gpio.h for
 desc_to_gpio()

Fixes this build error on sparc:

include/linux/of_gpio.h: In function 'of_get_named_gpio_flags':
include/linux/of_gpio.h:93:3: error: implicit declaration of function 'desc_to_gpio' [-Werror=implicit-function-declaration]
