From 4ba115b1e1ab6b717e08e0f4e766a1d16853d217 Mon Sep 17 00:00:00 2001 From: Eduardo Valentin Date: Wed, 14 Nov 2012 15:23:30 +0000 Subject: thermal: cpu cooling: allow module builds As thermal drivers can be built as modules and also the thermal framework itself, building cpu cooling only as built-in can cause linking errors. For instance: * Generic Thermal sysfs driver * Generic Thermal sysfs driver (THERMAL) [M/n/y/?] m generic cpu cooling support (CPU_THERMAL) [N/y/?] (NEW) y with the following drive: CONFIG_OMAP_BANDGAP=m generates: ERROR: "cpufreq_cooling_unregister" [drivers/staging/omap-thermal/omap-thermal.ko] undefined! ERROR: "cpufreq_cooling_register" [drivers/staging/omap-thermal/omap-thermal.ko] undefined! This patch changes cpu cooling driver to allow it to be built as module.
