Pull USB fixes from Greg KH:
 "Here are some small USB fixes for 5.10-rc7 that resolve a number of
  reported issues, and add some new device ids.

  Nothing major here, but these solve some problems that people were
  having with the 5.10-rc tree:

   - reverts for USB storage dma settings that broke working devices

   - thunderbolt use-after-free fix

   - cdns3 driver fixes

   - gadget driver userspace copy fix

   - new device ids

  All of these except for the reverts have been in linux-next with no
  reported issues. The reverts are "clean" and were tested by Hans, as
  well as passing the 0-day tests"
