patch 'baseband/acc100: fix close cleanup' 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 11/14/22. 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/c6b2befc2e3b11ba9bc9bad74bda285b3d2c4b3a

Thanks.

Kevin

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")
