netfilter: ecache: remove another indent level
... by changing: if (unlikely(ret < 0 || missed)) { if (ret < 0) { to if (likely(ret >= 0 && !missed)) goto out; if (ret < 0) { After this nf_conntrack_eventmask_report and nf_ct_deliver_cached_events look pretty much the same, next patch moves common code to a helper. This patch has no effect on generated code. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
