I have no good news for you, except that this is known problem and
solutions have been discussed, but no one has time to solve the problem in
a clever way.
IMHO, the whole internal linux-dvb-structure could be changed to do
delayed release (e.g. with kref). Today it is not possible to do this in
generic way (for all DVB devices), because the memory of the
dvb-structures is stored in the driver's state and thus is released there
on unplug (for USB), but the drivers have no direct access on the nodes
created by the architecture (which is good from one point of view), hence
no knowledge about the real use_count.
