There was NVMEM support added to of_get_mac_address, so it could now return ERR_PTR encoded error values, so we need to adjust all current users of of_get_mac_address to this new fact. Signed-off-by: Petr Štetiar <ynezz@xxxxxxx> --- Changes since v3: * IS_ERR_OR_NULL -> IS_ERR Changes since v4: * I've just blindly replaced IS_ERR_OR_NULL with IS_ERR in v4, but this was wrong, as I've just realized, that we still need to check for NULL in this particular case as well, so I've added back IS_ERR_OR_NULL check drivers/staging/octeon/ethernet.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/staging/octeon/ethernet.c b/drivers/staging/octeon/ethernet.c index 986db76..8847a11c2 100644 --- a/drivers/staging/octeon/ethernet.c +++ b/drivers/staging/octeon/ethernet.c @@ -421,7 +421,7 @@ int cvm_oct_common_init(struct net_device *dev) if (priv->of_node) mac = of_get_mac_address(priv->of_node); - if (mac) + if (!IS_ERR_OR_NULL(mac)) ether_addr_copy(dev->dev_addr, mac); else eth_hw_addr_random(dev); -- 1.9.1
