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

Hi Samuel,

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

drivers/built-in.o: In function `wm8400_i2c_probe':
wm8400-core.c:(.text+0x100165): undefined reference to `devm_regmap_init_i2c'
drivers/built-in.o: In function `wm8400_module_init':
wm8400-core.c:(.init.text+0xb43c): undefined reference to `i2c_register_driver'
drivers/built-in.o: In function `wm8400_module_exit':
wm8400-core.c:(.exit.text+0x655): undefined reference to `i2c_del_driver'

Probably caused by commit 96cd102ae039 ("mfd: Don't support non-modular
wm8400 build") which was introduced to fix other problems.  In this
build, CONFIG_I2C=m and CONFIG_REGMAP_I2C=m.

I have used the mfd tree from next-20120511 again for today.
