A note for future reference, not sure what you mean with driver
API here. If you mean the in kernel API, the kernel rules are
that we are always free to change that (Linux does not have a
stable driver API).

So if a header does not sit under include/uapi (indicating that
it is an userspace API) then a change like this is fine.

Regards,

Hans
