You sure don't :)

Try this patch. It runs against kernel source. I tried it on 2.6.32, 2.6.32-r1
and -r2. I basically did some general cleanup on the go7007 driver in the kernel
tree, added few standard v4l2 commands and *temporarily* put back in proprietary
go7007 ioctls from your package for continued mythtv support. I also added
support for ADS Tech DVD Xpress DX2 board (which was the main reason I got into
it). It runs well on my DX2 boxes. I've got about 100 of them and am currently
testing it on 5.
