linux-next: build failure after merge of the mfd tree

[Stephen Rothwell]

Hi Lee,

After merging the mfd tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/regulator/tps65086-regulator.c:194:9: error: implicit declaration of function 'regmap_write_bits' [-Werror=implicit-function-declaration]
   ret = regmap_write_bits(config->regmap,
         ^

Caused by commit

  23b92e4cf5fd ("regmap: remove regmap_write_bits()")

from the sound-asoc & regmap trees.

I am not sure why this is suddenly exposed by the mfd tree, but grep
would have been useful when the regmap tree patch was applied.

I have reverted that regmap commit for today.
