From: Kurt Roeckx Date: Sat, 14 Mar 2015 17:09:44 +0000 (+0100) Subject: Remove ssl_cert_inst() X-Git-Tag: OpenSSL_1_1_0-pre1~1541 X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=2c3823491d8812560922a58677e3ad2db4b2ec8d;p=openssl Remove ssl_cert_inst() It created the cert structure in SSL_CTX or SSL if it was NULL, but they can never be NULL as the comments already said.
