Thanks for redoing the patch. If Lee and Greg want to see it moved
here, I won't object, but I'd still like to understand the distinction better,
since there are likely going to be other drivers in the same situation
(either adding into misc or mfd) and it would be good if we can all
give consistent advice.

Greg, Lee: can you come up with a simple definition of what an
MFD is that this driver does not fit into? What about other
PCI drivers like intel-lpss-pci and lpc_ich? Are they different
from this one or should they also be moved out of MFD?

Arnd
