Do we really need the same line in the changelog twice?

Based on the "ls1021a_cmux" in the context it looks like this patch is
intended to apply on top of https://patchwork.kernel.org/patch/8923541/ but I
don't see any mention of that.

Please keep these lists of chips sorted (or as close as you can in the case of
the cmux structs which already have some sorting issues).
