[dpdk-stable] patch 'test: fix build with GCC 11' has been queued to stable release 19.11.9

[Christian Ehrhardt]

Hi,

FYI, your patch has been queued to stable release 19.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/12/21. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/640dec22b7869c8aea2b5310f0dd4dec664bc916

Thanks.

Subject: [PATCH] test: fix build with GCC 11

[ upstream commit 50eea2bfa79cc6bfef9014c2e0cb89d5a458969f ]

GCC 11 complains that 'a' is uninitialized.

../dpdk/app/test/test_prefetch.c: In function 'test_prefetch':
../dpdk/app/test/test_prefetch.c:25:9:
error: 'a' may be used uninitialized [-Werror=maybe-uninitialized]
   25 |         rte_prefetch0(&a);
      |         ^~~~~~~~~~~~~~~~~

Fix by initializing 'a'.

Bugzilla ID: 714
Fixes: af75078fece3 ("first public release")
