Merge tag 'usb-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB updates from Greg KH:
"Here's the big USB pull request for 3.14-rc1
Lots of little things all over the place, and the usual USB gadget
updates, and XHCI fixes (some for an issue reported by a lot of
people). USB PHY updates as well as chipidea updates and fixes.
All of these have been in the linux-next tree with no reported issues"
