Subject: [dpdk-dev] [PATCH v4 03/10] app/eventdev: clean LTO build warnings
(maybe-uninitialized)

Errors-To: dev-bounces@dpdk.org
Sender: "dev" <dev-bounces@dpdk.org>
During LTO build compiler reports some 'false positive' warnings about
variables being possibly used uninitialized. This patch silences these
warnings.
Exemplary compiler warning to suppress (with LTO enabled):
error: ‘service_id’ may be used uninitialized in this function
[-Werror=maybe-uninitialized]
ret = evt_service_setup(service_id);
