Subject: networkd: Free Prefix in case allocation fails (#7480)
X-Git-Tag: v236~108
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a86d329f225cbe093eefe1de37ac5cf2b53b8872;p=thirdparty%2Fsystemd.git

networkd: Free Prefix in case allocation fails (#7480)

Set the code to call _cleanup_prefix_free_ in case the next allocation
fails so that Prefix does not leak memory.
