The following patch implements support for the cx23885 based DViCO FusionHDTV DVB-T Dual Express2. It uses the dib7070 chipset, which was already supported by an existing usb adapter. Working on my pc but not extensively tested yet.
There is obviously a bit of code duplication due to the cut and paste from the usb adapter, and i'm not sure about the use of sec_priv.
Any pointers for refinement?
