driver writing sample/guide?

[Ben Wu <bwu@xxxxxxxxxxxx>]

Hi,

I'm in the process of writing a v4l2 driver for a custom video board. 
I've downloaded the sample driver (dated 20020330) from thedirks.org ftp 
site as well as the most recent headers and source (20030626). 
Unfortunately, the driver no longer compiles with the most recent 
version of the headers.

Is there an updated example driver/source that uses the new interface? 
The latest interface seems to have changed things around signficantly.

Thanks
