Otherwise looks good to me.

Damn, you're right, it's missing in both wm9705 and wm9712, but not in wm9713. That will be for the hopefully last volley of this serie. Thanks for spotting that. Cheers.

Given that this just missed the merge window but has now been reviewed by Takashi as well what I'm thinking is that it's going to be easiest to apply the start of it now so hopefully no need to respin the whole series so often.
