So far a list is used to track auto-detected clients per driver. The same functionality can be achieved much simpler by flagging auto-detected clients. Two notes regarding the usage of driver_for_each_device: In our case it can't fail, however the function is annotated __must_check. So a little workaround is needed to avoid a compiler warning. Then we may remove nodes from the list over which we iterate. This is safe, see the explanation at the beginning of lib/klist.c.
