Subject: l2tp: Fix set-but-unused variables.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8cb490144708ef295421d0601b0866623651a37e;p=openwrt%2Fstaging%2Fblogic.git

l2tp: Fix set-but-unused variables.

The variable 'ret' is set but unused in l2tp_nl_register_ops().

This was obviously meant to maintain error codes which are
returned to the caller, make it so.
