Small nit:

Hardware connected to a fieldbus comes in two distinct flavours:
- clients (e.g. thermometer, robotic arm) called "fieldbus devices"
- servers (e.g. a PLC) called "fieldbus controllers"

Their userspace APIs will probably differ quite a lot.

The userspace API created by the patch is only for clients a.k.a.
"fieldbus devices". That's why I'm writing 'fieldbus_dev' all over the place.

For simplicity, we could change that to just 'fieldbus'. But would this get
us in trouble when, at some point, we want to add a userspace API for
servers a.k.a. "fieldbus controllers" ?
