Hi Sam,

We register the ab8500 as an MFD device from db8500 code during Device Tree

the normal way. Here we force MFD device registration of the ab8500 only
when booting with Device Tree enabled.

Solves this issue:
WARNING: at fs/sysfs/dir.c:526 sysfs_add_one+0x88/0xb0()
sysfs: cannot create duplicate filename '/bus/platform/devices/ab8500-core.0'

Are you planning on taking this in any time soon? I'd really like to fix this bug for Linus in -next.

Kind regards,
