The sender's (your) signed-off-by should come last [1]. Also, what is the
participation of Guodong in this patch? If Guodong helped in writing the patch
there should also be a Co-developed-by tag for Guodong, as shown in [1].

Also, you should avoid making changes that don't have to do with the patch
itself. This patch is about fixing the reg names, so no need to touch the
formatting of addresses. It just adds noise.

Other than that,
