#     Pull USB/PHY updates from Greg KH:
#      "Here is the big USB/PHY driver pull request for 5.1-rc1.
#     
#       The usual set of gadget driver updates, phy driver updates, xhci
#       updates, and typec additions. Also included in here are a lot of small
#       cleanups and fixes and driver updates where needed.
#     
#       All of these have been in linux-next for a while with no reported
#       issues"
