Subject: crypto/openssl: remove useless check before freeing
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=2680b69c7bd577ac07c799304eb21bc8e72fc4cd;p=dpdk.git

crypto/openssl: remove useless check before freeing

Remove if() condition prior to calling BN_free() as
BN_free(a) does nothing if a is NULL.
