Subject: nft: Use ARRAY_SIZE() macro in nft_strerror()
X-Git-Tag: v1.8.4~35
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ffb339224f71871d015e4b57ea8dbaf9fd4f8aad;p=thirdparty%2Fiptables.git

nft: Use ARRAY_SIZE() macro in nft_strerror()

Variable 'table' is an array of type struct table_struct, so this is a
classical use-case for ARRAY_SIZE() macro.
