patch 'raw/cnxk_gpio: fix file descriptor leak' has been queued to stable release 22.11.8

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 22.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/19/25. 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/84163aa605d60776c13e7c1ce056eabedfa122bd

Thanks.

Luca Boccassi

Subject: [PATCH] raw/cnxk_gpio: fix file descriptor leak

[ upstream commit 67f0beaf0f5bf2cf239219c737ed8d93aaaaa673 ]

The function would leak file if fscanf failed.
There is a working version in other file, clone that.

Fixes: 0e6557b448fa ("raw/cnxk_gpio: add self test")
