We found the following warning when using W=1 to build kernel: drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:3634:6: warning: variable ‘ret’ set but not used [-Wunused-but-set-variable] int ret, coe = priv->hw->rx_csum; When digging stmmac_get_rx_header_len(), dwmac4_get_rx_header_len() and dwxgmac2_get_rx_header_len() return 0 only, without any error code to report. Therefore, it's better to define get_rx_header_len() as void. Signed-off-by: Luo Jiaxing <luojiaxing@huawei.com> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.
