Hello,

A very similar series was posted a while ago. Patches 1, 2 and 4 in this series are identical, except for this patch, which adds one more very nice refactoring,
The other series:
https://lore.kernel.org/linux-pci/20230626110226.GA569947@rocinante
What I can do would be to pick this patch and squash it with the other ones that are already applied. I will then attribute both you and Yang Li as the authors. Let me know if this is fine with you, Yangtao and Yang.
That said...

Are you sure about the variable name here? This might be a small copy-and-paste mistake that snuck up here. Have a closer look, or better yet, try to compile and test this. :)

Same as above.

This could be made such that the assignments are together.
