Subject: [PATCH net-next 07/16] netfilter: xt_CT: Remove redundant assignment to ret
Date: Wed,  2 Jun 2021 00:06:20 +0200	[thread overview]
Message-ID: <20210601220629.18307-8-pablo@netfilter.org> (raw)
In-Reply-To: <20210601220629.18307-1-pablo@netfilter.org>

From: Yang Li <yang.lee@linux.alibaba.com>

Variable 'ret' is set to zero but this value is never read as it is
overwritten with a new value later on, hence it is a redundant
assignment and can be removed

Clean up the following clang-analyzer warning:

net/netfilter/xt_CT.c:175:2: warning: Value stored to 'ret' is never read [clang-analyzer-deadcode.DeadStores]
