it should be

: dss_irq_handler_omap2,
I am seeing a crash on Panda, which gets rectified with this
change. The root cause is access to DSS_IRQSTATUS register in the
dss_irq_handler_omap3 handler, which is not valid for OMAP4.
That really doesn't look right. Let me translate the code you've just
written:
if (cpu_is_omap24xx())
handler = dss_irq_handler_omap3;
else
handler = dss_irq_handler_omap2;
Which means: if we have an OMAP24xx device, use the OMAP3 handler,
otherwise use the OMAP2 handler. That's got to be wrong.
I agree, that the logic seems counter-intuitive. I was doing a quick test.
However, to keep the correct sequence, the logic inside the respective
handlers need to be looked at.
