Why would you ever want runtime_wakeup to be false unless 
runtime_forbidden is true? Surely the point of runtime power management 
is to be transparent to the user, in which case remote wakeup is 
required?

Matthew, what makes you think remote wakeup is required?  Lots of
power-manageable devices don't support it at all (consider disk drives
or display screens).

Sorry, I meant in cases where remote wakeup is a sensible concept. For 
things like storage there's obviously no reason to require it, but for 
something like USB the absence of remote wakeup would effectively break 
the driver for most users.
