Subject: raw/ifpga/base: check null pointer
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=20077edf5f09961c7b4434bdd4d48c4353d65507;p=dpdk.git

raw/ifpga/base: check null pointer

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

Coverity issue: 367483
Fixes: a05bd1b40bde ("raw/ifpga: add FPGA RSU APIs")
