Thanks for fixing the style of lines you modified, ...

... here however I think we usually don't correct the style if the line
wouldn't be touched otherwise. But obviously this is up to FPU Maintainers.

You can use the existing local pointer "status". Similarly in other MSA
macros.

This change appeared here by mistake, isn't it?
