I pushed a patch that fixes the following build failures:

ERROR: "wm5102_aod" [drivers/mfd/arizona-irq.ko] undefined!
ERROR: "wm5102_irq" [drivers/mfd/arizona-irq.ko] undefined!
ERROR: "irq_set_chip_and_handler_name" [drivers/mfd/arizona-irq.ko] undefined!
ERROR: "wm5102_patch" [drivers/mfd/arizona-core.ko] undefined!
ERROR: "arizona_irq_init" [drivers/mfd/arizona-core.ko] undefined!
ERROR: "arizona_irq_exit" [drivers/mfd/arizona-core.ko] undefined!

This one:

ERROR: "arizona_dai_ops" [sound/soc/codecs/snd-soc-wm5102.ko] undefined!

comes from the fact that arizon_dai_ops is not an exported symbol while
snd-soc-wm5102 is built as a module. This is coming from Mark's sound tree.

Cheers,
Samuel.
