This series fixes the last few remaining issues reported when fw_devlink=on by default.
Patch 1 is just [6] pulled in without changes into this series. It reduces some unnecessary probe reordering caused by a combination of fw_devlink and existing device link code. This fixes some issue caused by fw_devlink=on with respect to DMAs and IOMMUs [1]. Patch 2 fixes a warning [2] present in code unrelated to fw_devlink. It was just exposed by fw_devlink. Jon, Patch 2 should address the issues you reported[2] even without [3]. Could you test this series please? Michael, I think Patch 1 should fix [4] without [5]. Can you test the series please? Geert/Marek, As far as I know, there shouldn't have any more issues you reported that are still left unfixed after this series. Please correct me if I'm wrong or if you find new issues.
