I know it's not related to this patch, but why in the world do you have
a wmb() here? That's really not needed, and is a sign that something is
really wrong here...

No need for this goto at all, just don't call your fix_vbus_dev_info()
call, and return the value given you, making this function a lot
simpler, with no goto even needed.
what a mess...
