Hi Conor,
I am sorry I forgot to add some context here... There is an ongoing
discussion on the dependent series about power supplies and Jonathan
asked me to send this series to see how to properly handle the supply
fix...
See  https://lore.kernel.org/all/20241014193701.40e3785a@jic23-huawei/

Julien
