From b29438f22c807d8a4bda6f0fb3e24318117906c0 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Mon, 17 Nov 2014 18:36:23 +0800 Subject: [PATCH] nios2: fix error handling of irq_of_parse_and_map Return value of irq_of_parse_and_map() is unsigned int, with 0 indicating failure, so testing for negative result never works.
