Yeah, really my mistake, I didn't consider what happens in the test there when iwlwifi is built but without CONFIG_IWLMVM and CONFIG_IWLMLD.

I think we should add those to actually run their kunit tests too, which would fix the build issue, and maybe even CONFIG_IWLDVM to increase coverage of the tests in iwlwifi itself. I can send a patch for that.

All that said, the patch that breaks it is in linux-next via iwlwifi-next but seems to actually have missed the cutoff for 6.18, so we're good for now and I suppose Miri can even squash the build fix into that later.
