Controls passed to Camera::start() are now correctly applied. This is needed to pass the per-frame-controls test. The code uses the return value of ipa->start() to return the initial controls and pass them to the sensor instead of the setSensorControls signal because setSensorControls is asynchronous and would reach the sensor too late.
