Subject: [PATCH net-next 7/7] netfilter: nftables: remove redundant assignment of variable err
Date: Sat,  6 Feb 2021 02:50:05 +0100	[thread overview]
Message-ID: <20210206015005.23037-8-pablo@netfilter.org> (raw)
In-Reply-To: <20210206015005.23037-1-pablo@netfilter.org>

From: Colin Ian King <colin.king@canonical.com>

The variable err is being assigned a value that is never read,
the same error number is being returned at the error return
path via label err1.  Clean up the code by removing the assignment.

Addresses-Coverity: ("Unused value")
