I lost the original b4 branch and re-enrolled the series for v4, which generated a new change-id. I should have carried the existing one over. I have restored the v3 change-id (20260817-qda-v2-78e2d1f10529) on the branch, and it will stay fixed for all future revisions of this series. v5 will use it. Note that v4 is a substantial rework of v3 (the custom bus and iommu patches are gone, the legacy shim is new and the series is reordered), so a range-diff against v3 would be of limited use; the "Changes in v4" section in the cover letter lists what changed and why. //Ekansh
