They're asking if drivers should set driver_data to NULL while
unbinding, which always struck me as a waste of time given that
nothing except a currently bound driver should be using driver_data.

Yeah, it's not needed, as nothing should rely on that.  However it's
also not hurting anything either.

Every time I see it it always sets off a red flag, partly because we
shouldn't need to bother at all and partly because to the extent it's
valuable it's not something we should be doing on a driver by driver or
even subsystem by subsystem basis.
