Subject: Re: [PATCH] power management: force pm_ops.valid callback to be assigned

Hi!
> This patch changes the docs and behaviour from "all states valid" to
> "no states valid" if no .valid callback is assigned. Users of pm_ops
> that only need mem sleep can assign pm_valid_only_mem without any
> overhead, others will require more elaborate callbacks.
>
> Now that all users of pm_ops have a .valid callback this is a safe
> thing to do and prevents things from getting messy again as they
> were before.
