Hi Scott,

I am able to register the IRQ now once I add the call irq_set_default_host in cpm2_pic.
But when I call enable_irq the code throws the below warning and gives exception in enable irq at 
spin_unlock_irqrestore(&desc->lock, flags); in enable_irq.


printk(KERN_WARNING "Unbalanced enable for IRQ %d\n", irq);

The IRQ is automatically enabled when you request it.  Only call
enable_irq() if you previously called disable_irq().
