The driver ought to claim local bus ownership of the slave it's communicating with. This is for multi-master setups. The slave (in theory) will deny access to masters who try to access the CFAM address space but who don't "own" the bus. As driver doesn't seem to perform any other teardown there is no need to "un-claim" ownership at teardown. Also I'm not aware of any multi-master setup using this driver so it shouldn't actually matter. Also, the hardware doesn't seem to enforce this despite being required in the specification...
