Do you mean
https://github.com/git/git/blob/master/Documentation/SubmittingPatches#L197
 ?
I didn't find any hard rules regarding this, but I'll keep it in mind.

IIUC, HPO Power's  _POST_PMU is triggered right before power down
(_PRE_PMD), hence it's pretty logical to mute the amplifier at this stage.
I can't quite see anything wrong here.

So no I didn't ignore your comment, I simply misinterpreted what you meant.
Because of the logical assumption, I thought you were talking the unmute
part in _PRE_PMU, which I did add in the changelog.

Again, what's the issue here?
