patch 'ethdev: fix build with LTO' has been queued to stable release 21.11.4

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/20/23. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/36cbdd704bef140db2e35afd727f090f0502f14f

Thanks.

Kevin

Subject: [PATCH] ethdev: fix build with LTO

[ upstream commit cdd7ab072d1e662b1d06840447e7d1b8ab8946e3 ]

When Link Time Optimization is enabled, compiler may
complain about "id" in eth_representor_cmp() being
uninitialized.

To suppress the warning it is enough to add explicit
initialization of the variable causing the issue.

Fixes: df7547a6a2cc ("ethdev: add helper function to get representor ID")
