From: Eduardo Valentin Date: Tue, 8 Nov 2016 05:09:02 +0000 (-0800) Subject: thermal: core: move cooling device sysfs to thermal_sysfs.c X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=45cf2ec99c160e5c33402521bcff1a585629230a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
