In this case, of_get_ethdev_address() returns +-EPROBE_DEFER to indicate the driver should be retried later. + +Currently the driver treats all errors equally and falls back to a +random MAC address. Fix this by propagating EPROBE_DEFER so the +driver probe is deferred until the nvmem cell becomes available. + +Signed-off-by: Burak Aydos +--- + drivers/net/ethernet/lantiq_xrx200.c | 2 ++ + 1 file changed, 2 insertions(+) + +--- a/drivers/net/ethernet/lantiq_xrx200.c ++++ b/drivers/net/ethernet/lantiq_xrx200.c +@@ -597,6 +597,8 @@ static int xrx200_probe(struct platform_ + } + + err = of_get_ethdev_address(np, net_dev); ++ if (err == -EPROBE_DEFER) ++ return err; + if (err) + eth_hw_addr_random(net_dev); +
