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.
