Hello Suraj,

As the author of that repo I confirme you that I'm not updating the
examples anymore. Looking at the commit history you can see that the
last one was about a year ago. An even there I only make sure that the
drivers compile cleanly but I didn't try it as Matthias says.

A long time ago I update the drivers for academic purposes but since
then I have ever used anymore.

Hope that someone can continue this forking my git tree since I think
the LDD3 books is one of the best for newbies to understand how Linux
drivers are developed.

BTW: I do have time to push patches is someone send to me to fix the issues.

Best regards,
