The function mlx5_query_nic_vport_qkey_viol_cntr() calls the function mlx5_query_nic_vport_context() but does not check its return value. This could lead to undefined behavior if the query fails. A proper implementation can be found in mlx5_nic_vport_query_local_lb().

Add error handling for mlx5_query_nic_vport_context(). If it fails, free the out buffer via kvfree() and return error code.

Fixes: 9efa75254593 ("net/mlx5_core: Introduce access functions to query vport RoCE fields") Cc: stable@vger.kernel.org # v4.5 Target: net

"net" should be written in subject and not like keyword. [PATCH v3] net/mlx5_core: Add error handling -> [PATCH net v3] net/mlx5_core: Add error handling
