From e6df4c3b75bbaf464fc5475a4bdc392ab500670b Mon Sep 17 00:00:00 2001
From: Kamil Dudka <kdudka@redhat.com>
Date: Thu, 5 Mar 2020 17:37:12 +0100
Subject: [PATCH] do not use IF_LINT for initialization of scalar variables
It triggers false positives in compilers and static analyzers
for no real benefit.
