[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/28/24. 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:

Subject: [PATCH] baseband/la12xx: forbid secondary process

[ upstream commit 95547dc69119154c85abfa7e8523e83a7ac05c9e ]

The la12xx driver do not have any checks for secondary process
and it causes the system to try to initialize the driver, causing
segmentation faults.
LA12xx driver do not support multi-processing.
Return when not called from Primary process.

Fixes: f218a1f92017 ("baseband/la12xx: introduce NXP LA12xx driver")
