Is your idea to get rid of .eesipr_value for devices that have values
that are the same as .eesr_err_check?
For example in sh_eth_dev_init():
sh_eth_modify(ndev, EESR, 0, 0);
mdp->irq_enabled = true;
- sh_eth_write(ndev, mdp->cd->eesipr_value, EESIPR);
+ if (mdp->cd->eesipr_value)
+ sh_eth_write(ndev, mdp->cd->eesipr_value, EESIPR);
+ else
+ sh_eth_write(ndev, mdp->cd->eesr_err_check, EESIPR);
