[v2,0/4] USB: fix runtime PM after driver unbind

Message

A recent change in USB core broke runtime-PM after driver unbind in
several drivers (when counting all USB serial drivers). Specifically,
drivers which took care not modify the runtime-PM usage counter after
their disconnect callback had returned, would now fail to be suspended
when a driver is later bound.

Greg, feel free to pick these up directly. The media patch has been
acked by Mauro.
