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.
