I don't know the specifics of the patch either since OP has not linked their patch nor the final kernel commit. I don't understand why being a private list would be a problem since they can just post their patch on their website. Maybe they're waiting for the fix to hit mainline first.
But when someone submits a patch to any of my OSS projects and I want to make modifications to it before I merge it, I either keep the original author as the Author and make myself as Co-Authored-By, or make myself the Author and keep the original author as Co-Authored-By, depending on how much change I had to make to the original patch. In either case I also have the original author review my version to get their approval of my version.
The only case where I would not credit the original author at all (or only as Reported-By) is if my version had absolutely nothing to do with their patch, say they fixed the symptom in file X and I fixed the cause in file Y.
Edit: https://news.ycombinator.com/item?id=37674872 found the patches. If it was my project I'd consider these in the Author/Co-Authored-By category because they're basically the same patch.
