I noticed that there's spaces instead of tabs to indent the '\' after
exynos990-r8s.dtb, unlike the rest of the entries. This patch also
uses spaces to indent the whole entry. If maintainers are fine with
it, then it's alright, but if there's a v6 you could change it to use
tabs for consistancy's sake.

Rest looks fine to me.

Best regards, Ivo.
