Merge tag 'usb-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB patches from Greg Kroah-Hartman:
 "Here's the big USB pull request for 3.10-rc1.

  Lots of USB patches here, the majority being USB gadget changes and
  USB-serial driver cleanups, the rest being ARM build fixes / cleanups,
  and individual driver updates.  We also finally got some chipidea
  fixes, which have been delayed for a number of kernel releases, as the
  maintainer has now reappeared.

  All of these have been in linux-next for a while"
