Can you compile v4l2-compliance straight from the v4l-utils.git master branch? Version 1.6 is too old, and for proper compliance testing you should always use the master branch. It probably won't matter for this -s test, but for the regular test (without -s) it does make a difference. If nothing else, using the master branch will make it easier for me to match up the line numbers that v4l2-compliance reports to the actual source. Thanks!
