Subject: [PATCH rdma-next 08/16] RDMA/mlx4: Delete unreachable code
Date: Tue, 29 Oct 2019 08:27:37 +0200	[thread overview]
Message-ID: <20191029062745.7932-9-leon@kernel.org> (raw)
In-Reply-To: <20191029062745.7932-1-leon@kernel.org>

From: Leon Romanovsky <leonro@mellanox.com>

All callers allocate MAD structures with proper sizes,
there is no need to recheck it.
