Subject: [dpdk-dev] [PATCH 07/10] net/e1000: fix maybe-uninitialized warnings for LTO build
Date: Thu, 5 Sep 2019 11:32:36 +0200 [thread overview]
Message-ID: <20190905093239.27187-8-amo@semihalf.com> (raw)
In-Reply-To: <20190905093239.27187-1-amo@semihalf.com>
During LTO build compiler reports some 'false positive' warnings about
variables being possibly used uninitialized. This patch silences these
warnings.
