Subject: Re: [PATCH 3/5] mfd: twl4030-power: Move power-related data closer
together in the header file

I dont really see the point of doing this, as you're not really gathering
scattered structures but rather moving a group of definitions up in the header
file.
If you dont mind I'll drop this one, unless Jean wants to take it.
Cheers,
Samuel.
