Merge tag 'usb-4.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB fixes from Greg KH:
"Here are a number of USB driver fixes for reported problems for
4.17-rc3.
The "largest" here is a number of phy core changes for reported
problems with the -rc1 release. There's also the usual musb and xhci
fixes, as well as new device id updates. There are also some usbip
fixes for reported problems as more people start to use that code with
containers.
All of these have been in linux-next with no reported issues, except
the last few new device ids, which are "obviously correct" :)"
