Subject: [PATCH rdma-next 06/16] RDMA/qib: Delete redundant memset for MAD output buffer
Date: Tue, 29 Oct 2019 08:27:35 +0200 [thread overview]
Message-ID: <20191029062745.7932-7-leon@kernel.org> (raw)
In-Reply-To: <20191029062745.7932-1-leon@kernel.org>
From: Leon Romanovsky <leonro@mellanox.com>
There is no need to clear MAD output buffer, because all
callers are calling process_mad() with cleared output buffer.
