This does not solve the problem with the timing of registration and 
unregistration. The attach and detach function do provide this.
If you do not have access to them or only get access to everything
after i2c registration you will have to patch things up like I
explained above (go through list of clients, etc.). Something similar
will also have to be done on exit of the DVB adapter driver.
