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.
