3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 4a102b4d144f0422eb8b0a59c7cb194bf12163a9 upstream.
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.
