Merge tag 'usb-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB updates from Greg KH:
"Here's the big pull request for USB and PHY drivers for 4.7-rc1
Full details in the shortlog, but it's the normal major gadget driver
updates, phy updates, new usbip code, as well as a bit of lots of
other stuff.
All have been in linux-next with no reported issues"
