patch 'examples/ip_pipeline: fix build with GCC 13' has been queued to stable release 22.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=28aa18157845bc4794713fc01bbb450cdf8357c8

Thanks.

[ upstream commit aae10e97710eb3b6a43a61e733ca0bbff47ab0c4 ]

Fix the following build issue by initializing req to NULL for
the local variable.

In function 'thread_msg_handle', inlined from 'thread_main' at
../examples/ip_pipeline/thread.c:3130:6:
../examples/ip_pipeline/thread.c:535:20: warning: 'req' may be used
uninitialized [-Wmaybe-uninitialized]
  535 |                 if (req == NULL)
      |                    ^
../examples/ip_pipeline/thread.c: In function 'thread_main':
../examples/ip_pipeline/thread.c:433:32: note: 'req' was declared here
  433 |         struct thread_msg_req *req;

Bugzilla ID: 1220
Fixes: a8bd581de397 ("examples/ip_pipeline: add thread runtime")
