Do it version by version to catch any breakage in functionality and would also enable to debug any isssues. Do not directly try to port it to 3.11 Regards, Saket Sinha On Thu, Aug 7, 2014 at 8:45 PM, Omkar Houddin <ophouddin22@gmail.com> wrote:

In general, we're very careful to make sure that if we change an API, that the new version has a different signature (new name, or different number of arguments, so on), so you'll get a compile error if you try to build under a newer kernel. Of course, if that involves a change in locking or something, it may require some heavy lifting to fix your stuff. But at least identifying what needs fixing is actually easy. So if you just compile it, and look at the errors, and for each error track down what changed, and make the relevant correction to your code, you should be good. Oh, and then submit the driver to mainline, so somebody *else* does that work for you - whenever somebody changes an API, it's their job to go through the entire tree and fix it everyplace. One less thing for you to do. :)
