Subject[PATCH v1 0/3] driver core: Set fw_devlink=on take II
From
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.
