Why would reading the value from the register be any less racy than keeping it in memory? And reading from memory is probably much faster than reading from an HDMI register, so I'm not sure what you mean with zero-cost. But I guess it is simpler, so in that sense the patch is ok. But please revise the description. Tomi
