Subject: [PATCH rdma-next v1 25/36] RDMA/mlx5: Delete impossible inlen check
Date: Mon, 27 Apr 2020 18:46:25 +0300	[thread overview]

In-Reply-To: <20200427154636.381474-1-leon@kernel.org>

From: Leon Romanovsky <leonro@mellanox.com>

The inlen is set to be above zero in all flows before
and can't be negative at this stage.
