patch 'dts: fix pass rate edge case in results' has been queued to stable release 24.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/17/25. 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/4ffa336f68f8e11d712f970338be9ef764038136

Thanks.

Kevin

Subject: [PATCH] dts: fix pass rate edge case in results

[ upstream commit 5dc5b2a5f67e655554b60a11e2f9f63ab13ad8d3 ]

Add condition to results.json pass rate generation
method which returns 0 as the pass rate when the suite
is skipped, rather than causing a divide by 0 error.

Fixes: 9f8a257235ac ("dts: improve test run result statistics")
