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

[Andrzej Ostruszka]

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);
