Merge tag 'usb-3.9-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB fixes from Greg Kroah-Hartman:
"Here are a number of tiny USB fixes and new USB device ids for your
3.9 tree.
The "largest" one here is a revert of a usb-storage patch that turned
out to be incorrect, breaking existing users, which is never a good
thing. Everything else is pretty simple and small"
