Should they? I'm pretty sure this is not the first time this comes up - there are several drivers and / or subsystems, that re-use driver objects. But finding in mail archives wouldn't be very easy. And it worked until now - why should we break it?

My problem case is the soc-camera framework. There device struct is embedded into the video client object, which are kept as long as the driver is loaded.
