But that is making it impossible to compile a kernel without any network stack for those platforms or we are going back to either enclosing the calls to phy_register_fixup{,_for_uid,_for_id} with #ifdef CONFIG_PHYLIB or if(IS_BUILTIN(CONFIG_PHYLIB)). And as you can see, it is quite error prone and is done only done for 2 platforms on a total of 6. I believe fixing that in phy.h is more foolproof.
