annotate LinkedList.c @ 73:32757e494675

Fixed bug that sets the wrong variable for fading in Pause. There still seems to be another bug related to fading though based on Johnson Lin's test case. Audio no longer stops and triggers the completion callback, but the volume doesn't seem to go up to max for long fade-ins. Still investigating.
