In addition to this, there are the same cases like this,
in this file as below. Please search other same cases.
For instance, 'grep' will be a good way to find it.

static void slic_adapter_set_hwaddr(struct adapter *adapter)
{
struct sliccard *card = adapter->card;

if ((adapter->card) && (card->config_set)) {
memcpy(adapter->macaddr,
card->config.MacInfo[adapter->functionnumber].macaddrA,
sizeof(struct slic_config_mac));
if (is_zero_ether_addr(adapter->currmacaddr))
memcpy(adapter->currmacaddr, adapter->macaddr,
ETH_ALEN);
if (adapter->netdev)
memcpy(adapter->netdev->dev_addr, adapter->currmacaddr,
ETH_ALEN);
}
}

Joe Perches,
These are not spotted by checkpatch.pl.
However, after modifying it as below, checkpatch warnings are
printed. Would you confirm it?

if (is_zero_ether_addr(adapter->currmacaddr))
memcpy(adapter->currmacaddr, adapter->macaddr, ETH_ALEN);
if (adapter->netdev)
memcpy(adapter->netdev->dev_addr, adapter->currmacaddr, ETH_ALEN);
}


Best regards,
Jingoo Han
