All patches you send need you S-o-b line. This is true whether you
modified the patch or not.

When modifying a patch someone else wrote, it's typical to include some
notes on what you changed, e.g.:

Signed-off-by: Original author <...>
[swarren: Fixed checkpatch warnings]
Signed-off-by: You <...>

Or perhaps for larger changes that don't inline between the S-o-b very
well, put it above all the S-o-b.
