I'll fix this up on applying if everyone is happy (can't see why the
won't be, but best to check!) Michael is clearly given as the author of driver
so should probably have been in the cc list. Whilst I might apply this directly
as maintainer I much prefer if I get an ack from the driver author as if nothing
else it gives me a warm fuzzy feeling ;)

Also patch title should mention that a) this is a staging driver, b) which adc driver it
applies to. I'll fix that up as well on applying it.

Thanks for the patch though, it would probably never have been noticed otherwise!
