Yes, I wasn't sure what to do here and expected some comments. Should the
strategy be that if there's a single error we discard the entire ELD by
setting the size to zero?
No issues for the other changes.

The intent was to read the ELD after the device is opened, I don't think the
ELD can change during playback, the updates can only happen on a pin-sensing
event. I can't think of a good reason why a notification would be needed?
