Subject: netfilter: rpfilter: Remove unused variable 'ret'.
X-Git-Tag: v6.1-rc1~170^2~138^2
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=72f5c89804636b5b4c8599354a92d6df8cff42cc;p=tomoyo%2Ftomoyo-test1.git

netfilter: rpfilter: Remove unused variable 'ret'.

Commit 91a178258aea ("netfilter: rpfilter: Convert
rpfilter_lookup_reverse to new dev helper") removed the need for the
'ret' variable. This went unnoticed because of the __maybe_unused
annotation.
