Subject[ 11/31] USB: cdc-acm: fix pipe type of write endpoint
Date
3.0-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().
