[dpdk-stable] patch 'net/vdev_netvsc: fix device cast' has been queued to LTS release 18.11.2

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to LTS release 18.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/01/19. 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 can be viewed on the 18.11 branch at:
	https://github.com/kevintraynor/dpdk-stable-queue.git

Thanks.

Kevin Traynor

Subject: [PATCH] net/vdev_netvsc: fix device cast

[ upstream commit cc7cd517b1a26f284112a5d6e5f40d6c63584930 ]

The return value from bus->find_device is a rte_device
which is not safe to cast to a rte_vdev_device structure.
It doesn't really matter since only being checked for NULL
but static checkers might find a bug here.

Fixes: 56252de779a6 ("net/vdev_netvsc: add automatic probing")
