Turns out, it needed yet another update. The failures were all due to the fact that the v4l2-compliance version being used on kernelci.org was lagging by a few days behind the media/master branch. It's a pretty rare issue, but it would be nice to have a way to avoid that. On the KernelCI side of things, we should start monitoring tests and rebuild them automatically rather than on a fixed weekly basis. On the kernel side of things, it would help if the tests were updated _before_ the changes were applied to the branch as otherwise there would still be a window for this kind of issue to occur. Generally speaking, what do you think would be the best way to fit the KernelCI v4l2-compliance test cycles into the media subsystem workflow?
