The DVB binding schema at the DVB core assumes that the frontend is a
separate driver.  Faling to do that causes OOPS when the module is
removed, as it tries to do a symbol_put_addr on an internal symbol,
causing craches like:

    "Attach bug is fixed, tuning works, module unloads without
     crashing. Everything seems ok!"
