I added a new patch to my series:

https://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux.git/commit/?h=device-id-rework&id=29d6b8c50b1ace81f79e44c6a276dceee5297546

I won't resent just now, but in the assumption that the build bots will
find some more issues, wait a bit to reduce the number of patch
submissions.

Best regards
Uwe
