The only place where this variable would be set to false is the ksz8_config_cpu_port() function. But it is done in a bogus way: for (i = 0; i < dev->phy_port_cnt; i++) { if (i == dev->phy_port_cnt) <--- will be never executed. break; p->on = 1; So, we never have a situation where p->on = 0. In this case, we can just remove it.
