Ensure the Interrupt handling routine return IRQ_HANDLED vs
IRQ_NONE.

Why?

By unconditionally returning IRQ_HANDLED, this patch will surely break
systems where the UART IRQ is shared with other platforms.

I just noticed this patch when bisecting a related problem.  Why
wasn't this Cc'd to linux-omap where OMAP users might have been more
likely to see it?

Greg, without a better justification in the changelog, I think this
patch should be dropped from tty-next.

Now reverted, sorry for the delay.
