It was sort of cryptic, I'm not entirely sure I can make sense of it
either. It think I was mainly suggesting that it looked more like a
bool function so we could just return true/false, but we are actually
setting the of_reset function as part of this, so there is a 'get'
aspect. Feel free to ignore this comment. Thanks,
