Hi,
There isn't a way to pass the patch through to coverity through our scripting with how we have it written currently. It probably wouldn't be a big update to start running it based on a given patch provided, if you think there may be a somewhat regular need for this. I assume in this case we would not want to push the result to the coverity website, but rather just print out the result (to be shared on the mailing list or whatnot).
Otherwise, presumably it would be possible for us to manually spin up our coverity container image, apply the series, and run the coverity check.
I see you have merged this though. I will go ahead and trigger a coverity run now, just so that you get the results faster. Sorry about the wait here.
