Merge tag 'usb-4.8-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg KH:
 "Here are two small fixes, and one new device id, for 4.8-rc7

  The fixes solve a build error that was reported in your tree for the
  blackfin arch, and resolve an issue with a number of broken USB
  devices that reported the wrong interval rate.  Included here is also
  a new device id for the usb-serial driver.

  All have been in linux-next with no reported issues"

* tag 'usb-4.8-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb:
  USB: change bInterval default to 10 ms
  usb: musb: Fix tusb6010 compile error on blackfin
  USB: serial: simple: add support for another Infineon flashloader
