From 5030ec730279eabafccf862f3c8393af90c258a5 Mon Sep 17 00:00:00 2001 From: Bob Liu Date: Thu, 23 Jun 2011 17:09:49 -0400 Subject: USB: gadget: fix req length in sourcesink_setup() The recent commit 2edb11cbac fixed req->length in the composite_setup() function, but that will cause all g_zero tests to fail like: root#> ./testusb -D /proc/bus/usb/002/021 -t14 -c 15000 -s 256 -v 1 unknown speed /proc/bus/usb/002/021 /proc/bus/usb/002/021 test 14 --> 32 (Broken pipe) We need to fix req->length in sourcesink_setup() as well to avoid this.
