title: linux kernel patch signed-off-by line
body: <p>Basically, I'm stuck on task 4 of the Eudyptula challenge.</p>
  
  <p>I ran the submission through checkpatch.pl. The only error I got was from a missing signed-off-by line.</p>
  
  <p>I added the signed-off-by line, ran it through checkpatch.pl again, and it received no errors so I submitted the patch. I received a reply that says the scripts for this task can't handle patches.</p>
  
  <p>I removed the diff lines so that only the code and the signed-off-by line were left, and the submission still didn't pass.</p>
  
  <p>Has anybody else on here completed this task?</p>
