patch 'raw/cnxk_gpio: fix out-of-bound access for negative GPIO' has been queued to stable release 24.11.9

Hi,

FYI, your patch has been queued to stable release 24.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/26. 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/8a44a14989c8f227e7b9ae1a8ea04d8b735452ac

Thanks.

Luca Boccassi

Subject: [PATCH] raw/cnxk_gpio: fix out-of-bound access for negative GPIO

[ upstream commit 6700cb27d91b3b2e7a1f192d22d9e6004db08863 ]

cnxk_gpio_valid(struct cnxk_gpiochip *gpiochip, int gpio)
validates the GPIO number with only an upper bound while gpio
can be wrongly configured as negative value from application.
Added a check to reject negative values.

Fixes: ecc0dd455e9a ("raw/cnxk_gpio: add option to select subset of GPIOs")
