Why this change?
It is not documented in the patch description.

   This unneeded init of ret should be in a separate patch.

   This is a separate issue too. I thought I've removed this myself
but apparently not, the commit [1] took shamefully long time to merge... :-(

   This change also looks good (but undescribed!), however it should be
done in a separate patch.
   For the future, try to follow a simple rule: do one thing per patch.
Oh, and don't forget to describe everything you do in a patch...
