It can wait until the next RC of v6.2. Ok, I'll take this to wireless tree. > Kalle - should I send a pull request for it? Thanks! For patches to the wireless tree I prefer that I take them directly. What I recommend is to assign the patch to me on patchwork and add "v6.2" to the subject like this: [PATCH v6.2] wifi: iwlwifi: fw: skip PPAG for JF That way I'll then apply it automatically. But this for future patches, I have now assigned this patch to me.
