In add_badrange() or badblocks_populate(), the list_empty() branch does the same things as the code after list_for_each_entry(). And the list_for_each_entry() will do noting when list_empty().
So the list_empty() branch can be removed without functional change, let the code after list_for_each_entry() to do it.
