I meant something like this:

dispc.c:

dispc_init()
{
        /* did we have a pdev for dispc? if not, this needs to be dss.pdev */
        request_irq(platform_get_irq(dispc.pdev, 0), irq_handler, IRQF_SHARED, 
"dispc irq", foo);
}

irq_handler()
{
        if (irq_can_be_shared) {
                check if the irq is for us. exit if not;
        }

        handle;
}

dsi.c:

dsi_init()
{
        request_irq(platform_get_irq(dsi.pdev, 0), irq_handler, IRQF_SHARED, "dsi 
irq", foo);
}

irq_handler()
{
        if (irq_can_be_shared) {
                check if the irq is for us. exit if not;
        }

        handle;
}


This approach looks clean, but isn't IRQF_SHARED used the other way 
around. One irq line and multiple handlers?
