Hm, I just noticed that this patch is marked "Not Applicable" in patchwork:

https://patchwork.kernel.org/project/linux-pci/patch/39f87c99f6c44be3c0371c79e454e6fde7be0d4d.1761497583.git.lukas@wunner.de/

It didn't get any on-list replies and didn't get applied AFAICS.
I'm not sure why it's marked this way in patchwork or what to do about it.

There's one other patch sharing the same fate:

https://patchwork.kernel.org/project/linux-pci/patch/75e4ae507fa4faddd063a3a9e17d319ed84529b6.1757562971.git.lukas@wunner.de/

Thanks!
