what's wrong with it ? it's a err msg? how to avoid it, maybe my kernel config or dts is incorrect?

and i note that dir of '/sys/devices/system/cpu/cpu0' doesn't contain the dir of 'cpufreq ', but have the dir of '/sys/devices/system/cpu/cpufreq', it's empty in it

BSP is Board Support Package. We have Yocto and Android BSP.
