[dpdk-stable] patch 'raw/ioat: fix missing close function' has been queued to stable release 19.11.6

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/30/20. 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.

Thanks.

Luca Boccassi

Subject: [PATCH] raw/ioat: fix missing close function

[ upstream commit 8c6cedee761c7abd8c3d451bffa7c70747ab7629 ]

When rte_rawdev_pmd_release() is called, rte_rawdev_close() looks for a
dev_close function for the device causing a segmentation fault when no
close() function is implemented for a driver.

This patch resolves the issue by adding a stub function ioat_dev_close().

Fixes: f687e842e328 ("raw/ioat: introduce IOAT driver")
