Subject: [PATCH nf-next v4 02/10] netfilter: bitwise: remove NULL comparisons from attribute checks.
Date: Wed, 15 Jan 2020 21:32:08 +0000 [thread overview]
Message-ID: <20200115213216.77493-3-jeremy@azazel.net> (raw)
In-Reply-To: <20200115213216.77493-1-jeremy@azazel.net>
In later patches, we will be adding more checks. In order to be
consistent and prevent complaints from checkpatch.pl, replace the
existing comparisons with NULL with logical NOT operators.
