If CONFIG_NF_CONNTRACK_ZONES is not defined, the variable ret might be uninitialized when it goes to err1 through line 125 and 263 respectively. So I change these goto err1 to return -EINVAL directly. Signed-off-by: Cong Ding <redacted> --- net/netfilter/xt_CT.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
