Subject: [PATCH for-next 1/7] RDMA/hns: Fix query destination qpn
Date: Thu, 26 Aug 2021 21:37:30 +0800 [thread overview]
Message-ID: <1629985056-57004-2-git-send-email-liangwenpeng@huawei.com> (raw)
In-Reply-To: <1629985056-57004-1-git-send-email-liangwenpeng@huawei.com>
The bit width of dqpn is 24 bits, using u8 will cause truncation error.
Fixes: 926a01dc000d ("RDMA/hns: Add QP operations support for hip08 SoC")
