From 45cf2ec99c160e5c33402521bcff1a585629230a Mon Sep 17 00:00:00 2001 From: Eduardo Valentin Date: Mon, 7 Nov 2016 21:09:02 -0800 Subject: thermal: core: move cooling device sysfs to thermal_sysfs.c This is a code reorganization, simply to concentrate the sysfs handling functions in thermal_sysfs.c. This patch moves the cooling device handling functions.
