Merge tag 'usb-3.3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB merge for 3.4-rc1 from Greg KH:
"Here's the big USB merge for the 3.4-rc1 merge window.
Lots of gadget driver reworks here, driver updates, xhci changes, some
new drivers added, usb-serial core reworking to fix some bugs, and
other various minor things.
There are some patches touching arch code, but they have all been
acked by the various arch maintainers."
