Hi Stephen,

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

In file included from drivers/mfd/ab8500-core.c:21:0:
include/linux/mfd/dbx500-prcmu.h:614:19: error: redefinition of 'prcmu_abb_read'

Caused (exposed?) by commit d28f1db8187d ("mfd: Remove confusing
ab8500-i2c file and merge into ab8500-core"). I assume that this has
only had very restricted build testing :-(

The patch itself has had extensive build and run testing, with DT both enabled and disabled. I'm guessing some other changes may be having and influence here. I'm happy to take a look for you. Can you tell me where I can pull the offending branch from please?

Kind regards,
Lee
