patch 'bus: cleanup device lists' has been queued to stable release 22.11.9

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 22.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/25. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/a025a6346bc564be08c5314cbd63242156af512c

Thanks.

Luca Boccassi

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

[ upstream commit 398bb775edc5434ad94578a5e6c49fa1328acc0f ]

Although eal_bus_cleanup() is not invoked for multiple times, this is a
good programming habit to remove the device object from list when
cleanup bus.

Fixes: 1cab1a40ea9b ("bus: cleanup devices on shutdown")
Fixes: 62b906cf06ba ("bus/uacce: introduce UACCE bus")
Fixes: 65780eada9d9 ("bus/vmbus: support cleanup")
