patch 'common/cnxk: fix null SQ access' has been queued to stable release 24.11.4

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/26/25. 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/4d8505348c48426722d3c8fd6a54dd543aef7c45

Thanks.

Kevin

Subject: [PATCH] common/cnxk: fix null SQ access

[ upstream commit 52ff61c2ca114691d74546f5ce16e8a7ebd164ae ]

Condition to check SQ is non NULL before access. Also pktio locks
are simplified while doing threshold_profile config.

Fixes: 90a903ffa6eb ("common/cnxk: split NIX TM hierarchy enable API")
