patch 'dma/cnxk: fix device state' has been queued to stable release 21.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/08/23. 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/f2a2d57884c625c0a86223d6a2f4b722ff70d19b

Thanks.

Kevin

Subject: [PATCH] dma/cnxk: fix device state

[ upstream commit 190b2239b801d84179e5f57a1dda7ed19539281c ]

When a device is not set to a ready state, on exiting the application
proper cleanup is not done. This causes the application to fail on
trying to run next time.

Setting the device to ready state on successful probe fixes the issue.

Fixes: 53f6d7328bf4 ("dma/cnxk: create and initialize device on PCI probing")
