Other side can be a remote processor (for remoteproc over virtio or
something similar), or traditionally it can be host OS or host
firmware providing virtualisation to a Guest running Linux (this
driver). Or something else..
I would incline towards "we trust the other side" here.

The other side is the software that has access to the _Real_ hardware,
and so we should trust it. So we can have a actually have a completion
without timeout here, interesting.
