Merge tag 'usb-3.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg Kroah-Hartman:
 "Here are the USB patches against your 3.7-rc1 tree.

  There are the usual UABI header file movements, and we finally are now
  able to remove the dbg() macro that is over 15 years old (that had to
  wait for after some other trees got merged into yours during the big
  3.7-rc1 merge window.)

  Other than that, nothing major, just a number of bugfixes and new
  device ids.  It turns out that almost all of the usb-serial drivers
  had bugs in how they were handling their internal data, leaking
  memory, hence all of those fixups.
