dev->chipid is used in lan78xx_init_mac_address before it's initialized:

lan78xx_reset() {
lan78xx_init_mac_address()
lan78xx_read_eeprom()
lan78xx_read_raw_eeprom() <- dev->chipid is used here

dev->chipid = ... <- dev->chipid is initialized correctly here
}

Reorder initialization so that dev->chipid is set before calling
lan78xx_init_mac_address().
