You can't just change code without understanding _why_ you are changing
it. You just changed the logic here, why do you think it is ok that
BUG() is no longer called? Are you properly cleaning up and recovering
here now that WARN_ON() is called?
checkpatch.pl is a hint, you can't just blindly do whatever it says, you
still have to think.
