how to use dvb_attach (was: Re: [linux-dvb] Re: Error unloading
WinTV NOVA T USB2)

The wrong use_count for the dib3000mc is most likely because I'm not using
the dvb_attach-function for attaching the demod/frontend, because the
prototype of the dib3000mc_attach is not exactly the same as for other
Why? Because with the dib3000mc_attach (and with the future coming
dib7000m_attach and dib7000p_attach) we can attach more than one demod at
the same time - will be used on devices arriving late fall/autumn).
Can someone please advise me how to proceed?
thanks in advance,
