[dpdk-stable] patch 'eal: fix device iterator when no bus is selected' has been queued to stable release 20.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/12/21. 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/steevenlee/dpdk

This queued commit can be viewed at:

Subject: [PATCH] eal: fix device iterator when no bus is selected
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit fc382022c6adcde57eb30e58186198275ad493d7 ]

Devargs used in device iterator initialization wasn't set to zero, random
data like bus string lead to invalid address access.

This patch initializes devargs.

Bugzilla ID: 862
Fixes: c99a2d4c6b7f ("eal: implement device iteration initialization")
