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. :)
