Hi Samuel,

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

ERROR: "arizona_dai_ops" [sound/soc/codecs/snd-soc-wm5102.ko] undefined!
ERROR: "wm5102_aod" [drivers/mfd/arizona-irq.ko] undefined!

ERROR: "arizona_irq_init" [drivers/mfd/arizona-core.ko] undefined!
ERROR: "arizona_irq_exit" [drivers/mfd/arizona-core.ko] undefined!

I have used the mfd tree from next-20120706 for today.
