So fix for v1 doorbells is coming? Yes I've root caused the doorbell breakage in V1 API to commit 7c3ded5735141ff4d049747c9f76672a8b737c49. I'll send out a fix soon. Thanks, Gautam

So the tag should be Cc: stable@vger.kernel.org # v6.7+ and not Cc: stable@vger.kernel.org # v6.7 Should I send a new version of this series or can you please make this change when pulling in your tree?
