patch 'raw/ifpga: fix build with optimization' has been queued to stable release 21.11.1

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/22/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/dec4b1b89ec3e34c26537e3acd76b628d75d7253

Thanks.

Kevin

Subject: [PATCH] raw/ifpga: fix build with optimization

[ upstream commit 047c25401d2b4001e7e20200a5ec05868a113290 ]

Compile failed with cflag optimization=1 on Ubuntu20.04 with GCC10.3,
it reported vendor_id and dev_id may be used uninitialized in function
ifpga_rawdev_fill_info().
Actually it's not the truth, the variables are initialized in function
ifpga_get_dev_vendor_id(). To avoid such compile error, the variables
are initialized when they are defined.

Fixes: 9c006c45d0c5 ("raw/ifpga: scan PCIe BDF device tree")
