Okay, if this is a concern I will have to keep my changes off the
mainline as it is a required feature.

My interest is to fake sensor values for the guest and not to connect
anything to real hardware. I think I misinterpreted your "chardev". To
clarify: My guest is a bare metal ARM image, no linux and I don't want
to interact with the host's hardware. So no chardev in the linux sense
is involved.
Anyway thank you for your feedback.
