Hi,

FYI, your patch has been queued to stable release 20.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/07/22. 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/e9703e47a796aa10a239d4555c56d27f8db9bb09

Thanks.

Luca Boccassi

Subject: [PATCH] baseband/acc100: fix close cleanup

[ upstream commit ba2262fe16cade81a18b353d580ec4229e1020a6 ]

Set local pointer to NULL after rte_free.
This needs to be set explicitly since logic may check for null pointers.

Fixes: 060e7672930 ("baseband/acc100: add queue configuration")
