Subject: [PATCH] tipc: Drop unused variable 'genl'

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1602555
Upstream Status: iproute2.git commit 8d05f33a381a2

commit 8d05f33a381a22572341204c667aafca02aabcca
Author: Phil Sutter <phil@nwl.cc>
Date:   Thu Oct 18 15:48:09 2018 +0200

    tipc: Drop unused variable 'genl'

    Although initialized by call to libmnl, the variable is used only in a
    call to sizeof(). Drop it and call sizeof with its type instead.

    Fixes: f043759dd4928 ("tipc: add new TIPC configuration tool")
