Surely this is just what normal set voltage calls do? If devA says
set_voltage(v1, v2) but devB still has set_voltage(v2, v2) then we will
leave the voltage at v2, we'll only allow it to be set to v1 if both
consumers agree that this is a valid voltage. It feels like there's
something else going on here that I'm missing?
