You need a single patch - hopefully much is already handled by the
backports project?

Ideally, you don't patch your driver at all, but extend the backport
(include files, compat.ko module) to provide the APIs that your driver
needs but that don't exist on older kernels. Sometimes, patching (the)
driver(s) is unavoidable, in which case semantic patches would be
preferred.

However, you can start with a patch and we can help you disentangle it.
