Arnd Bergmann e8d39240d6 thermal: cpu_cooling: fix stub function
The function stub for cpufreq_cooling_get_level introduced
in 57df81069 "Thermal: exynos: fix cooling state translation"
is not syntactically correct C and needs to be fixed to avoid
this error:

In file included from drivers/thermal/db8500_thermal.c:20:0:
 include/linux/cpu_cooling.h: In function 'cpufreq_cooling_get_level':
include/linux/cpu_cooling.h:57:1:
 error: parameter name omitted  unsigned long cpufreq_cooling_get_level(unsigned int, unsigned int)  ^
 include/linux/cpu_cooling.h:57:1: error: parameter name omitted
