The point I was making wasn't so much about using the MFD API itself as
about the fact that I'd expect the bit of the device driver that sits
under drivers/mfd to know about all the subdevices that needed
registering, especially for things which don't usually need any system
specific configuration.  I'd probably not have said anything if the
original code hadn't taken the entire list of subdevices in as platform
data.
