"device info is absolutely required" *only* for IOVA=VA mode, so user may skip
to provide it.

> Any thoughts or ways to address this without device.?

Return error if 'iova_mode' requested but device info not?

But you didn't replied to passing 'iova_mode' from application, I would like
hear what you are thinking about it..

I understand that part.
What I am suggestion is something like this:

kva = common_function(kni, kni->pa[i]);

---

common_function() {
	if (unlikely(kni->iova_mode == 1))
		return iova2kva(kni, kni->pa[i]);
	return pa2kva(kni->pa[i]);
}

To hide the check in the function and make code more readable
