Subject: [PATCH v7 0/2] net/mlx5: Fix NULL dereference and memory leak in ttc_table creation

This patch series addresses two issues in the
mlx5_create_inner_ttc_table() and mlx5_create_ttc_table() functions:

1. A potential NULL pointer dereference if mlx5_get_flow_namespace()
returns NULL.

2. A memory leak in the error path when ttc_type is invalid (default:
switch case).

Henry Martin (2):
  net/mlx5: Fix null-ptr-deref in mlx5_create_{inner_,}ttc_table()
  net/mlx5: Move ttc allocation after switch case to prevent leaks
