From 217fb00a7947a4ac0da15ab7a32d2aeb2fa5539a Mon Sep 17 00:00:00 2001 From: Chanho Park <chanho61.park@samsung.com> Date: Thu, 11 Feb 2016 23:11:20 +0900 Subject: [PATCH] drm/exynos: use DIV_ROUND_CLOSEST to find the closest div This patch uses DIV_ROUND_CLOSEST instead of DIV_ROUND_UP The DIV_ROUND_CLOSEST can be used to find the closest integer value when we divide some integers.
