As discussed in the previous patches, its far better to have MACROS or
enums instead of having 0/1/2 cases. As a matter of fact, we can always
call it RING_0 RING_1 and so on.
If this is being done just for the traditional reasons, we can have a
separate patch to replace it across the driver as well.
