The patch is mostly mechanical, with a couple exceptions:
 - getters/setters were not removed even if only one of
   them is being used
 - versioning API was also left in place
They will be added back on an as-needed basis.

Mixing two memory management systems, in this case
managed device resource api and refcounted objects
is a bad idea. Lifetime of an object is controlled
by its refcount so allocating it with other apis
that have their own lifetime control is not ok.
Drop devm_*() apis in favor of plain allocations.

The find_dev_index() function is frustrating.  If you give it an invalid
index then it returns 0.  That was the intent except there is an
off-by-one so it can return MAX_NIC_TYPE which is one higher than we
want.

There is one caller which had a sanity check to catch invalid returns,
but the other two callers assumed that index was valid.

My feeling is that when we are given invalid indexes, that should be
treated like an error and we abandon what we were doing.
