3.4-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().
