Subject: MINOR: mt_lists: Appease gcc.
X-Git-Tag: v2.2-dev5~81
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=49983a9fe11840e0fc14a96e4097ad56cc2d06c8;p=thirdparty%2Fhaproxy.git

MINOR: mt_lists: Appease gcc.

gcc is confused, and think p may end up being NULL in _MT_LIST_RELINK_DELETED.
It should never happen, so let gcc know that.
