Subject: [dpdk-dev] [PATCH v1 4/4] raw/ifpga/base: check pointer before dereferencing
Date: Wed, 17 Mar 2021 04:21:36 -0400
Message-ID: <1615969296-17021-5-git-send-email-wei.huang@intel.com> (raw)
In-Reply-To: <1615969296-17021-1-git-send-email-wei.huang@intel.com>

In init_sec_mgr(), pointer "hw" may be NULL, so "hw" should
be checked before dereferencing.

Coverity issue: 367483
Fixes: 7a4f3993f269 ("raw/ifpga: add FPGA RSU APIs")
