Again b) is sufficient in my opinion. All bus_ops are for cards, while
host_ops are for hosts.

Also, there may be some corner cases where b) can't be done, like the
->remove() bus_ops for example. In that case, we either have to make
more re-structuring of the code of simply live with that there may be
some special cases.
