If your PR contains a patch:

• [√] It can be applied using git am
• [√] It has been refreshed to avoid offsets, fuzzes, etc., using

  make package/<your-package>/refresh V=s

• [√] It is structured in a way that it is potentially upstreamable
  _{(e.g., subject line, commit description, etc.)
  We must try to upstream patches to reduce maintenance burden.}

@hnyman I'm so sorry that I'm not a experienced git user. When I tried to amend my commit to fix the CI test errors, I accidentally closed the previous PR (#28866), so I had to open a new one.
And I have now fixed it according to the CI test log.

I missed a small change when comparing the patch file😥, and it has now been fixed.
The new patch file has been tesed, and I will squash commits into one for clarity.
