patch 'crypto/qat: fix build with GCC 12' has been queued to stable release 21.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/01/22. 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/29b6bd601428a25e37b282f09e4b4a2244e111d9

Thanks.

Kevin

Subject: [PATCH] crypto/qat: fix build with GCC 12

[ upstream commit 04361fe2aca8998ea06fb4823dceb965698e147c ]

GCC 12 raises the following warning:

Added a check to prevent compiler warnings.

Fixes: 1703e94ac5ce ("qat: add driver for QuickAssist devices")
