ADI's website says that these parts are obsolete, so unless anyone is
actually still using these with a mainline kernel, I would suggest that
we drop the driver rather than spending time fixing it up.

In any case, unless you have the hardware for testing, it would be
best not to make significant changes. There is a non-standard "oti"
attribute that we would need to figure out what to do with. This is
likely why the driver is in staging in the first place.
