Summary
cppc_cpufreq: Fix possible null pointer dereference
Details

In the Linux kernel, the following vulnerability has been resolved:

cppc_cpufreq: Fix possible null pointer dereference

cppccpufreqgetrate() and hisicppccpufreqgetrate() can be called from different places with various parameters. So cpufreqcpu_get() can return null as 'policy' in some circumstances. Fix this bug by adding null return check.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
