Merge tag 'usb-4.10-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB fixes from Greg KH:
"Here are a bunch of USB fixes for 4.10-rc3. Yeah, it's a lot, an
artifact of the holiday break I think.
Lots of gadget and the usual XHCI fixups for reported issues (one day
that driver will calm down...) Also included are a bunch of usb-serial
driver fixes, and for good measure, a number of much-reported MUSB
driver issues have finally been resolved.
All of these have been in linux-next with no reported issues"
