Subject: raw/cnxk_gpio: check pointer before use in self test
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=ee05a93e1e6633d0fdec409faf09f12a2e05b991;p=dpdk.git

raw/cnxk_gpio: check pointer before use in self test

Even though nonexistent cnxk_gpio is unlikely at this point
it's a good practice to check pointers before using them.

Fixes: 0e6557b448fa ("raw/cnxk_gpio: add self test")
Coverity issue: 376502
