Thanks Bjorn for catching this. This change originally was developed by Tarak, but I sent upstream based on his patch so I missed

to update his name as author. I should update author name.

However, if we are going to squash this in first patch, then I think, first patch's author will stay as it is.

Following Action Item on me for v5:

1) Fix commit text in first patch.

2) Squash second patch in first.

3) Add my s-o-b signature after Mathieu's

4) Add Tarak's s-o-b as well. As he developed second patch.

Hope got it all.


Thanks,

Tanmay
