You're right. I'll remove the extra blank line.

I'm not sure I fully understand what you meant by that comment. This
conversion preserves the existing behavior, so although checking rv
and returning ret may look a bit odd, I don't think it changes the
behavior or introduces a bug.

As you suggested,
I'll remove the ret variable entirely and return IRQ_NONE /
IRQ_HANDLED directly.
