[dpdk-stable] patch 'bus/pci: fix leak for unbound devices' has been queued to stable release 20.11.3

Hi,

FYI, your patch has been queued to stable release 20.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/14/21. 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/dbf34013549a5e32691c90bdb84e80fffaf96868

Thanks.

Luca Boccassi

Subject: [PATCH] bus/pci: fix leak for unbound devices

[ upstream commit 7c83a1e3c83e601f449f05e2e36e1df50e8503aa ]

For devices not bound to any Linux kernel module, we leak a pci object
since it is never added to the PCI bus device list.

Fixes: c79a1c67465d ("bus/pci: optimize bus scan")
