It's important to have an overview of what the > series does. You are absolutely right. I'm sorry! On a 1 or 2 patch series I don't like seeing cover letters, but on a 3+ patches, specially on the first submission I believe it is important. And it helps maintainers to writing the pull-request notes later. Thanks for the review and for the note, Rodrigo. > > Thanks, > Andi

Although these functions are used in runtime_pm, they are not exclusively used there, so remove the misleading prefix.
