From e83863d3e7ead8c66c1cabb53d95ebd3c7f1805e Mon Sep 17 00:00:00 2001 From: Ming Lei <ming.lei@canonical.com> Date: Tue, 16 Oct 2012 21:21:21 +0800 Subject: USB: cdc-acm: fix pipe type of write endpoint commit c5211187f7ff8e8dbff4ebf7c011ac4c0ffe319c upstream. If the write endpoint is interrupt type, usb_sndintpipe() should be passed to usb_fill_int_urb() instead of usb_sndbulkpipe().
