From: Cosmin Ratiu <redacted> Currently, clearing a vport's parent happens with a call that looks like this: mlx5_esw_qos_vport_update_parent(vport, NULL, NULL); Change that to something nicer that looks like this: mlx5_esw_qos_vport_clear_parent(vport); Signed-off-by: Cosmin Ratiu <redacted> Reviewed-by: Carolina Jubran <redacted> Signed-off-by: Tariq Toukan <tariqt@nvidia.com> --- .../ethernet/mellanox/mlx5/core/esw/devlink_port.c | 2 +- drivers/net/ethernet/mellanox/mlx5/core/esw/qos.c | 11 +++++++++-- drivers/net/ethernet/mellanox/mlx5/core/eswitch.h | 3 +-- 3 files changed, 11 insertions(+), 5 deletions(-)
