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 (powerpc
allyesconfig) failed like this:

drivers/gpio/gpio-zevio.c: In function 'zevio_gpio_port_get':
drivers/gpio/gpio-zevio.c:70:2: error: implicit declaration of function 'IOMEM' [-Werror=implicit-function-declaration]
  return readl(IOMEM(c->chip.regs + section_offset + port_offset));
  ^

Caused by commit 9af4d80ba566 ("gpio: New driver for LSI ZEVIO SoCs").

I have reverted that commit for today.
