I generally try to prevent people from adding more ad-hoc interfaces
to drivers/misc. Anything that is called a drivers/misc driver to me
must qualify as "there can't possibly be a second driver with the
same semantics", otherwise it should be part of another subsystem
with clear rules, or be put into its own file system.

While it seems that right now everyone is just trying to keep move
the driver to some other subsystem, I think it's worth noting that
it is indeed a useful thing to have the driver, I'm optimistic
that we can find some place for it. ;-)

Now how about the IIO stuff? This is the first time I've even
heard about it. Does it have any major disadvantages besides
being staging-quality?
