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

Hi all,

After merging the final tree, today's linux-next build (powerpc
ppc44x_defconfig) failed like this:

In file included from include/asm-generic/gpio.h:13:0,
from include/linux/gpio.h:51,
from include/linux/of_gpio.h:20,
from arch/powerpc/sysdev/ppc4xx_gpio.c:29:
include/linux/gpio/driver.h:85:14: error: 'struct seq_file' declared inside parameter list [-Werror]
include/linux/gpio/driver.h:85:14: error: its scope is only this definition or declaration, which is probably not what you want [-Werror]

Caused by commit 79a9becda894 ("gpiolib: export descriptor-based GPIO
interface") from the gpio tree.

I have applied this fix up patch for today:

Subject: [PATCH] gpiolib: provide a declaration of seq_file in gpio/driver.h

Fixes this build error:
