Please read and follow Documentation/process/submitting-patches.rst.

Especially this paragraph:

  Describe your changes in imperative mood, e.g. "make xyzzy do frotz"
  instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy to
  do frotz", as if you are giving orders to the codebase to change its
  behaviour.

I asked for this over and over and no, I'm not going to fixup your changelogs
again.
 
Thanks,
