patch 'bus/cdx: fix device name in probing error message' has been queued to stable release 23.11.6

[Shani Peretz]

Hi,

FYI, your patch has been queued to stable release 23.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/30/25. 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/shanipr/dpdk-stable

This queued commit can be viewed at:
https://github.com/shanipr/dpdk-stable/commit/0ecbe4610ed359f9e5bec77203fbcb9a63146ecc

Thanks.

Shani

Subject: [PATCH] bus/cdx: fix device name in probing error message

[ upstream commit ebd507b220b58ff8e2e87d1c2fce51cb1d4420d1 ]

The variable cdx_addr is a stack-allocated zero-initialized char array, but
it is never used anywhere, except as part of error message out. The
intention is to display device name, so fix the code to reflect that.

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