3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit d535922691fc026479fcc03e78ac3d931a54e75a upstream.
There is a bug in mvebu_gpio_probe() where we do:
mvchip->irqbase = irq_alloc_descs(-1, 0, ngpios, -1);
if (mvchip->irqbase < 0) {
The problem is that mvchip->irqbase is unsigned so the error handling
doesn't work. I have changed it to be a regular int.
