Depends on how much you have changed the code. If the change is
significant then change the authorship to you and drop my signed-off.
Else, keep the authorship and signed-off.
If you are adding something new to the patch like adding code to make
sure that only 32bit data reads are issued, then I suggest you to submit
that change as separate patch.
