Subject: Fix anonymous connection_state pointer
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b7da05ec20128b45b4b97c769562f8db76ec14be;p=thirdparty%2Fcollectd.git

Fix anonymous connection_state pointer

Returning an anonymous pointer (which is limited to the scope of the
function) causes a build error with -Werror.
