3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ming Lei <ming.lei@canonical.com>
commit c5211187f7ff8e8dbff4ebf7c011ac4c0ffe319c upstream.
If the write endpoint is interrupt type, usb_sndintpipe() should be passed to usb_fill_int_urb() instead of usb_sndbulkpipe().
