I'd say it only makes sense if we do it for all busses ... so USB and PCI would have to move too. Logically, the bus code should move and we should be left with the drivers in both of those directories. I'd also say that we don't have to deepen the tree: /bus would be fine. That way, /drivers/<bus> would be only for <bus> specific drivers, with non bus specific drivers we just group them by function as now. What about the half busses (like SCSI)? Finally, is there any real point (other than we can do it)? what is actually helped by having the bus code obviously separated from the driver code (assuming we sort out what is bus and what is driver)?
