Merge tag 'usb-3.11-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB fixes from Greg KH:
"Here are some small USB fixes for 3.11-rc6 that have accumulated.
Nothing huge, a EHCI fix that solves a much-reported audio USB
problem, some usb-serial driver endian fixes and other minor fixes, a
wireless USB oops fix, and two new quirks"
