Subject: [PATCH rdma-next] RDMA/rxe: Remove useless rxe_init_device_param assignments
Date: Sun, 20 Oct 2019 08:57:24 +0300	[thread overview]
Message-ID: <20191020055724.7410-1-leon@kernel.org> (raw)

From: Leon Romanovsky <leonro@mellanox.com>

IB devices are allocated with kzalloc and don't need explicit zero
assignments for their parameters. It can be removed safely.
