From 0c980826211611178b6d76b246d00a4c840f21e5 Mon Sep 17 00:00:00 2001 From: Sachin Kamat Date: Thu, 21 Feb 2013 16:42:27 -0800 Subject: [PATCH] drivers/video/exynos/exynos_mipi_dsi.c: fix an error check condition Checking an unsigned variable for negative value returns false. Hence use the macro to fix it. Fixes the following smatch warning: drivers/video/exynos/exynos_mipi_dsi.c:417 exynos_mipi_dsi_probe() warn: unsigned 'dsim->irq' is never less than zero.
