  "USB fixes for 4.19-rc7

   Here are some small USB fixes for 4.19-rc7

   These include:
     - the usual xhci bugfixes for reported issues
     - some new serial driver device ids
     - bugfix for the option serial driver for some devices
     - bugfix for the cdc_acm driver that has been there for a long time.

   All of these have been in linux-next for a while with no reported
   issues."
