Subject: [PATCH] RDMA: remove useless condition in siw_create_cq()
Date: Mon, 11 Jul 2022 18:12:51 +0300	[thread overview]
Message-ID: <20220711151251.17089-1-strochuk@ispras.ru> (raw)

Comparison of 'cq' with NULL is useless since
'cq' is a result of container_of and cannot be NULL
in any reasonable scenario.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Signed-off-by: Andrey Strachuk <strochuk@ispras.ru>
Fixes: 303ae1cdfdf7 ("rdma/siw: application interface")
