There isn't a bug for it right now, I have only some vague memory that I saw such error messages when dealing with some other bugs some time ago. So perhaps I shouldn't add the stable tag, sorry for that, this seems to belong to the 'this patch solves a potential problem' case... For the 1/3 patch, no crash either. It's just that if CONFIG_PM_RUNTIME is not set, ZPODD will not function so building it doesn't make sense.
