Subject: drivers/mailbox/omap: make mbox->irq signed for error handling

There is a bug in omap2_mbox_probe() where we try do:

		mbox->irq = platform_get_irq(pdev, info->irq_id);
		if (mbox->irq < 0) {

The problem is that mbox->irq is unsigned so the error handling doesn't
work.  I've changed it to a signed integer.
