For the kernel.org I think you need an account @kernel.org (which itself requires your key to be signed by someone), but I am not sure.
I am happy to move entire development to github and keep kernel.org only for releases till some distro packages notice the change. If Github, then your linux-nfc looks indeed nicer.

Thanks! I managed to do some testing with nfc-sim modules, although I am not sure how much is supported.

I just sent one more set :)
