USB serial updates for 7.4-rc1

Here are the USB serial updates for 7.4-rc1:

 - fix urb leak on sierra write completion
 - fix urb leak on usb_wwan disconnect
 - fix data corruption due to missing mxuport tx throttling
 - add support for two new classes of mxuport devices
 - add support for rs485 to mxuport
 - add new modem device ids
 - replace the last __get_free_page() with kmalloc()

Everything has been in linux-next with no reported issues. The mxuport
changes were merged yesterday, but they were contributed by a competent
vendor (and passed my smoke test).
