From: Colin Ian King Date: Fri, 18 Aug 2017 13:49:25 +0000 (+0100) Subject: mlx5: ensure 0 is returned when vport is zero X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1547f538c14581346c2eb82f8af0071ee6ec2b30;p=openwrt%2Fstaging%2Fblogic.git mlx5: ensure 0 is returned when vport is zero Currently, if vport is zero then then an uninialized return status in err is returned. Since the only return status at the end of the function esw_add_uc_addr is zero for the current set of return paths we may as well just return 0 rather than err to fix this issue.
