Hi,

FYI, your patch has been queued to stable release 20.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/23/23. 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/7f305f7b108912d6fcf1ce5618378092cd298d71

Thanks.

Luca Boccassi

Subject: [PATCH] bus/ifpga: fix devargs handling

[ upstream commit 8a0b28b4d9581497d7b347c7c8797317707cd58f ]

In function ifpga_scan_one(), variable 'path' is NULL if device argument
'afu_bts' is not set, subsequent string copy with 'path' would lead to
segmentation fault.

Fixes: 6fa4aa2b3645 ("bus/ifpga: fix forcing optional devargs")
