There seems to be some confusion over in the thread for v1 of this patchset.
Perhaps relating to several similar patches being in-flight at the same
time.

1. Changes were requested by Florian
2. Jakub confirmed this concern
3. Florian Acked v1 patch
4. The bot sent a notificaiton that v1 had been applied

But v1 is not in net-next.
And I assume that 3 was intended for v2.

From my point of view v2 addresses the concerns raised by Florian wrt v1.
And, moreover, I agree this fix is correct.

v2 is marked as Changes Requested in patchwork.
But I suspect that is due to confusion around v1 as summarised above.
So I am (hopefully) moving it back to Under Review.


v1 was applied already, which, per the discussion on the systemport driver appears to be the correct way to go about:
