[ACPI] [PATCH] make cpu_has_cpufreq() work

[Dirk M. <dmu...@su...>]

Hi, 

it seems to me the return values of cpu_has_cpufreq in processor_thermal.c are 
reversed. all callers check for if(!cpu_has_cpufreq()) return -ENODEV, which 
indicates that it expects a return value of 0 for error, and nonzero for 
success. 

However the current implementation gets that reversed. the patch below fixes 
it. Spotted by Thomas Renninger, and fixes the ACPI thermal code never 
actually speedstepping the CPU when it overheats.
