USB fixes for 4.16-rc3

Browse Source 
Here are a number of USB fixes for 4.16-rc3
 
 Nothing major, but a number of different fixes all over the place in the
 USB stack for reported issues.  Mostly gadget driver fixes, although the
 typical set of xhci bugfixes are there, along with some new quirks
 additions as well.
 
 All of these have been in linux-next for a while with no reported
 issues.
