Subject: [nf-next PATCH v2 2/5] netfilter: bitwise: replace hard-coded size with `sizeof` expression
Date: Mon,  4 Apr 2022 13:04:14 +0100	[thread overview]
Message-ID: <20220404120417.188410-3-jeremy@azazel.net> (raw)
In-Reply-To: <20220404120417.188410-1-jeremy@azazel.net>

When calculating the length of an array, use the appropriate `sizeof`
expression for its type, rather than an integer literal.
