The warning is legit though:
572 if (dsa_port_is_cpu(port))
573 err = dsa_cpu_parse(port, index, dst, ds);
> 574 else if (dsa_is_normal_port(port))
575 err = dsa_user_parse(port->dn, index, ds);
and after applying your patches I also met it:
net/dsa/dsa2.c: In function 'dsa_ds_parse':

'dsa_is_normal_port' from incompatible pointer type [enabled by default]

We need something like this, I have some comments on your patches that I
