3.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ming Lei <redacted>

commit c5211187f7ff8e8dbff4ebf7c011ac4c0ffe319c upstream.

If the write endpoint is interrupt type, usb_sndintpipe() should
be passed to usb_fill_int_urb() instead of usb_sndbulkpipe().
