I think the usb_disconnect() comment update is pretty straightforward,
though more comment updates may be warranted.
The changes so usb_add_hcd() and usb_remove_hcd() don't hold the
usb_bus_list_lock around usb_disconnect() need more scrutiny from you
experts. It *appears* unnecessary to me, and I'm pretty sure that other
callers (hub_quiesce() and hub_port_connect_change()) do not hold
usb_bus_list_lock while calling usb_disconnect(). But I know next to
nothing about the USB locking scheme.
