Combined with the previous patch, you are now marking all devices that
happen to be attached to a root hub that is on a thunderbolt controller
as removable.  So all USB devices inside of a docking station are now
removable?

What type of devices did you test this series out with?  And again, what
problem are you trying to solve?
