With the patch applied, both the CHV and the ICL branches of the if
statement include these 3 seq_printf() calls.
The patch is "adding" these printfs to the CHV part of the if, but if
you see below it "moves" the printfs that were originally part of CHV
to ICL. I think it's just a case of diff organizing things in a
different way than a human would.
Now, if we don't want to print these things on ICL too, then that's an
error.
