Hi,

FYI, your patch has been queued to stable release 24.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/22/26. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/8b8a91c87489107cc79a27cc17ffbfe15c47b8d6

Thanks.

Luca Boccassi

Subject: [PATCH] net/dpaa: fix device remove

[ upstream commit c468b4374d92c32222a796f3ddffd6b741012d36 ]

Add a check to avoid closing a device that is already closed,
preventing a double-close condition during device removal.

Note: this also removes the explicit dpaa_finish() call that was
made at last-device remove time (!dpaa_valid_dev). dpaa_finish() is
registered as RTE_FINI_PRIO(dpaa_finish, 103) and will still run at
process exit, so for the normal run-then-exit path behaviour is
unchanged. For a remove-all-then-re-probe scenario, is_global_init
will remain set until exit; re-probe in a running process is not a
supported use case for this driver.

Fixes: 78ea4b4fcb52 ("bus/dpaa: improve cleanup")
