However, this code was introduced by 

commit 91be260faaf8561dc51e72033c346f6ab28d40d8
Author: Nicolas Sugino <nsugino@3way.com.ar>

    [media] dib8000: Add support for Mygica/Geniatech S2870
    
    MyGica/Geniatech S2870 is very similar to the S870 but with dual tuner. The card is recognised as Geniatech STK8096-PVR.
