[christian.ehrhardt@canonical.com]

Hi,

FYI, your patch has been queued to stable release 19.11.12

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/27/22. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/47065be22622b9634d2bb0be00bd21097eb42e37

Thanks.

Subject: [PATCH] bus/ifpga: remove useless check while browsing devices

[ upstream commit 62c21c38a26e654bba09be147ea2d61c2e699a13 ]

reported by code analysis tool C++test (version 10.4):

  /build/dpdk-20.11/drivers/bus/ifpga/ifpga_bus.c
  67    Condition "afu_dev" is always evaluated to true
  81    Condition "afu_dev" is always evaluated to true

The "for" loop already checks that afu_dev is not NULL.

Fixes: 05fa3d4a6539 ("bus/ifpga: add Intel FPGA bus library")
