From c55930e33eba7003fea9890cf755b28e201dd037 Mon Sep 17 00:00:00 2001 From: Amit Daniel Kachhap Date: Tue, 25 Jun 2013 17:11:42 +0530 Subject: [PATCH] thermal: exynos: use device resource management infrastructure This patch uses the device pointer stored in the configuration structure and converts to dev_* prints and devm API's.
