I think this should be fixed by:

commit 4f5747cf8e5947479a27a3597829e45d6d8d73e0

    RDMA/mlx5: Fix -Wformat warning in check_ucmd_data()
    
    Variables of type size_t should use %zu rather than %lu [1]. The variables
    "inlen", "ucmd", "last", and "size" are all size_t, so use the correct
    format specifiers.
