USB fixes for 4.16-rc6 

Here are a small clump of USB fixes for 4.16-rc6.
 
 Nothing major, just a number of fixes in lots of different drivers, as
 well as a PHY driver fix that snuck into this tree.  Full details are in
 the shortlog.
 
 All of these have been in linux-next with no reported issues.
