From 5153c120fa6c368c4e9a28d9a5864c91fbfb15c3 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 7 Nov 2013 10:50:19 +0300 Subject: [PATCH] gpio: mvebu: make mvchip->irqbase signed for error handling 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.
