Subject: linux-next: build failure after merge of the gpio tree

Hi all,

After merging the gpio tree, today's linux-next build (x86_64
allmodconfig) failed like this:

ERROR: modpost: "of_pinctrl_get" [drivers/gpio/gpio-tegra186.ko] undefined!

Caused by commit

  b64d6c9a6a05 ("gpio: tegra186: Add support for pin ranges")

and not fixed by commit

  e45ee71ae101 ("pinctrl: Define of_pinctrl_get() dummy for !PINCTRL")

CONFIG_OF=y
CONFIG_PINCTRL=y
CONFIG_GPIO_TEGRA186=m

I applied this patch:
