Ah, right, it's been superseded by 
https://patchwork.ozlabs.org/project/linuxppc-dev/patch/20220609133245.573565-1-mpe@ellerman.id.au/

So I mark the new one superseded as well.

By the way, is your other patch still applicable, ref 
https://patchwork.ozlabs.org/project/linuxppc-dev/patch/20220610102821.252729-1-ariel.miculas@belden.com/ 
?

Thanks
Christophe
