Well that was a waste of my time. I was originally making 
patches against the video4linux CVS. 

Based on some of the responses to my post of my first patch 
I thought I was not supposed to make patches for 
video4linux CVS because this is a dvb driver. So I got the 
mm kernel and merged everything into that at the proper 
locations to create the patch I started this thread with. 

I also worked out the Kconfig stuff so that you could select 
the driver with a kernel configuration program. While doing 
this I discovered the nasty little secret that makes it 
impossible to create a cx88-dvb that is configured for only 
one of the dvb drivers.

I'll do that tomorrow.

I'll take a swipe at that tomorrow just for the heck of it.

That is what I tried to do for my driver with the original 
patch I sent on this thread. I made changes to files in 
both the video and dvb subdirectories.

How about just checking out the files from cvs and making my 
changes. Change to the video4linux directory. Then produce 
a patch with something like this:

cvs diff -upPN

The above may not be exactly right, but I'll experiment a 
bit and get it to work.

Good point. I tend to forget to verify that the patch 
applies properly.

I just need the driver for my own card. I am glad to share 
it.
