"-device foo" is really shorthand for "-device driver=foo".  And deep
down in the bowels of qdev, where the error get reported, the value of
parameter "driver" gets treated like any other parameter's value: if
it's not within ACCEPTABLE-SET, complain "Parameter 'NAME' expected

Overuse of syntactic sugar considered harmful.
