Hi Samuel,

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

ERROR: "wm8400_block_read" [drivers/regulator/wm8400-regulator.ko] undefined!
ERROR: "regmap_reinit_cache" [drivers/mfd/wm8400-core.ko] undefined!

Caused by commit 4d240045599c ("mfd: Remove wm8400 custom cache
implementation").

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