Subject: [NETFILTER]: xt_tcpudp: fix double unregistration in error path
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9abdcf6b6cf387035d934c77bf9ebe5e747166f9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[NETFILTER]: xt_tcpudp: fix double unregistration in error path

"xt_unregister_match(AF_INET, &tcp_matchstruct)" is called twice,
leaving "udp_matchstruct" registered, in case of a failure in the
registration of the udp6 structure.
