From 42b696e808bbea3a4ebf8029e1965d2314612402 Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Tue, 24 Feb 2015 13:56:54 +0900 Subject: thermal: exynos: Fix wrong control of power down detection mode for Exynos7 This patch fixes the wrong control of PD_DET_EN (power down detection mode) for Exynos7 because exynos7_tmu_control() always enables the power down detection mode regardless 'on' parameter.
