Hi all,

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

drivers/mfd/88pm800.c: In function 'pm800_pages_init':
drivers/mfd/88pm800.c:434:2: error: implicit declaration of function 'IS_ERR' [-Werror=implicit-function-declaration]
  if (IS_ERR(subchip->regmap_power)) {
  ^
drivers/mfd/88pm800.c:435:3: error: implicit declaration of function 'PTR_ERR' [-Werror=implicit-function-declaration]
   ret = PTR_ERR(subchip->regmap_power);
   ^

Caused by commit f8ca616f67f7 ("mfd: 88pm800: Enhance error handling for
sub pages probe/remove") from the mfd tree.  Forgot to include
linux/err.h (see Rule 1 in Documentation/SubmitChecklist).

I have reverted that commit for today.
