Hi,

FYI, your patch has been queued to stable release 19.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before December 10th 2021. 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/3cc36e068b4298160caa9e77c5545bd8f8e019f6

Thanks.

Subject: [PATCH] power: fix build with clang 13

[ upstream commit 0353121c33846c40ff2e2282448f324c93d3ce9d ]

clang-13 rightfully complains that the tot_ppi variable in update_stats
is set but not used, since the final accumulated tot_ppi results isn't
used anywhere.

Fixes: 450f0791312c ("power: add traffic pattern aware power control")
