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.
