So the kbuild robot said that it couldn't apply the patch on net, so
it tried on net-next and hit some further W=1 warnings.
So I've fixed the warnings and targeted the patch against net-next:
https://patchwork.ozlabs.org/project/netdev/cover/20200530102953.692780-1-olteanv@gmail.com/
(I don't think anybody should care enough that they should deal with
the resulting conflicts from targeting against net).

Thanks,
