[dpdk-stable] patch 'vhost: remove unneeded null pointer check' has been queued to LTS release 16.11.9

[Luca Boccassi]

Hi,

FYI, your patch has been queued to LTS release 16.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/21/18. 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. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Luca Boccassi

Subject: [PATCH] vhost: remove unneeded null pointer check

[ upstream commit 0541588a44bff07e4aae4c9cde8586326955c378 ]

The caller will guarantee that msg won't be null. Remove
the unneeded null pointer check which caused a Coverity
warning.

Coverity issue: 323484
Fixes: 8f972312b8f4 ("vhost: support vhost-user")
