      xhci: If no endpoints changed, don't issue BW command. · 2dc37539
      Sarah Sharp authored
      Some alternate interface settings have no endpoints associated with them.
      This shows up in some USB webcams, particularly the Logitech HD 1080p,
      which uses the uvcvideo driver.  If a driver switches between two alt
      settings with no endpoints, there is no need to issue a configure endpoint
      command, because there is no endpoint information to update.
      
      The only time a configure endpoint command with just the add slot flag set
      makes sense is when the driver is updating hub characteristics in the slot
      context.  However, that code never calls xhci_check_bandwidth, so we
      should be safe not issuing a command if only the slot context add flag is
      set.
