V4L/DVB (6037): Updated GenPix USB driver
There are now 4 different versions of the GENPIX USB adapter. The
newest 'Skywalker' models are fully self-contained, and need no
additional hardware to be used. A very reliable DVB-S card even without
using any of the alternate modulatations (which this kernel module does
not currently support)
The following patch adds support for all 4 versions of the genpix
adapter (www.genpix-electronics.com).
