Hi Linus,

After merging the gpio tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/gpio/gpio-uniphier.c:324:14: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
  .activate = uniphier_gpio_irq_domain_activate,
              ^

Caused by commit

  dbe776c2ca54 ("gpio: uniphier: add UniPhier GPIO controller driver")

interacting with commit

  72491643469a ("genirq/irqdomain: Update irq_domain_ops.activate() signature")

from the tip tree

I added the following merge fix patch:
