Dan Carpenter report: The patch f47e04eb96e0: "net/mlx5: E-switch, Allow setting share/max tx rate limits of rate groups" from May 31, 2021, leads to the following Smatch static checker warning: drivers/net/ethernet/mellanox/mlx5/core/esw/qos.c:483 esw_qos_create_rate_group() warn: passing zero to 'ERR_PTR' If min rate normalization failed then error code may be overwritten to 0 if scheduling element destruction succeed. Ignore this value and always return initial one. Fixes: f47e04eb96e0 ("net/mlx5: E-switch, Allow setting share/max tx rate limits of rate groups") Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Dmytro Linkin <dlinkin@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
