Hi Balaji,

Building kernel 2.6.29-rc1-git4 on x86_64 with CONFIG_MFD_PCF50633=m
fails at linking time with:

ERROR: "__set_irq_handler" [drivers/mfd/pcf50633-core.ko] undefined!
ERROR: "handle_level_irq" [drivers/mfd/pcf50633-core.ko] undefined!

Yes, I've seen this. The fix is waiting on linux-mfd to be pulled
anytime soon.

Where is linux-mfd? And what is it, a git tree, a mailing list? I
couldn't find any reference.

Can you please send me the patch now, so that I can fix my build
locally right now?

Thanks,

Would you be so kind and write a patch adding this information to
MAINTAINERS? And get it upstream, so that developers know where it is.
