Subject: [PATCH for-next 5/7] RDMA/hns: Delete unnecessary memset when allocating VF resource
Date: Mon, 27 Jul 2020 16:10:47 +0800
Message-ID: <1595837449-29193-6-git-send-email-liweihang@huawei.com> (raw)
In-Reply-To: <1595837449-29193-1-git-send-email-liweihang@huawei.com>

From: Lang Cheng <chenglang@huawei.com>

The hns_roce_cmq_setup_basic_desc() can clear the whole desc, so removes
these redundant memset operations.
