The series as a whole builds fine according to the same report, and this code is not modified by later patches. It looks a lot like this report from yesterday: https://www.spinics.net/lists/netdev/msg709132.html Which also seemed unrelated to the changes: https://www.spinics.net/lists/netdev/msg709264.html Thanks!
