Again, I am not sure if the Fixes tag makes sense. Although the issue was
there when the driver birth, there are some more commits after then.

Given that:
- The patch is a minor fix (see [1][2]).
- There is no specific commit the patch aims to fix.
I prefer to drop the Fixes tags. In any case, I don't think the tags would be

I would defer to Mark.
