patch 'bus/cdx: fix release in probing for secondary process' 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/8bd7087215b9f9a96a9d6c0e0b848668e51a9bf9

Thanks.

Kevin

Subject: [PATCH] bus/cdx: fix release in probing for secondary process

[ upstream commit ad13df8e9379c5f17e6548eca1ae829f71795fde ]

The variable cdx_addr is a stack-allocated zero-initialized char array, but
it is never used anywhere except in an error handler to stand it as a
device bus address for a VFIO device release call. This is incorrect, as it
should have been actual device address, so fix the code to reflect that.

Fixes: 45ef232af515 ("bus/cdx: introduce AMD CDX bus")
