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

Hi Linus,

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

drivers/extcon/extcon-palmas.c:211:25: error: too few arguments to function 'devm_gpiod_get_optional'
  palmas_usb->id_gpiod = devm_gpiod_get_optional(&pdev->dev, "id");
                         ^

                 from /home/sfr/next/next/include/linux/of_gpio.h:20,

 struct gpio_desc *__must_check devm_gpiod_get_optional(struct device *dev,
                                ^

Caused by commit

  b17d1bf16cc7 ("gpio: make flags mandatory for gpiod_get functions")

interacting with commit

  92b7cb5dc885 ("extcon: palmas: Support GPIO based USB ID detection")

from the extcon tree.

I have applied this merge fix patch for today:
