i was thinking since the device_unregister() is called everywhere, maybe 
there are some other drivers missing that too?

and the driver calls device_add(), then the core attaches the device to 
the driver automatically, maybe it would make sense to let the core 
automatic detach it somehow...

but i know nothing about driver core, maybe i should fix it in spi core, 
i'll send new patch for that :)
