From f0d564230e08d314aac54cbcb1865a4b8fafe906 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Fri, 17 Nov 2017 18:35:53 +0000 Subject: [PATCH] irqchip/qcom: Fix u32 comparison with value less than zero [ Upstream commit e9990d70e8a063a7b894c5cbb99f630a0f41200d ] The comparison of u32 nregs being less than zero is never true since nregs is unsigned. Fix this by making nregs a signed integer.
