Jinjie RuanandGreg Kroah-Hartman c923c437ed cpufreq: mediatek-hw: Fix wrong return value in mtk_cpufreq_get_cpu_power() ...

commit 172bf5ed04 upstream.

mtk_cpufreq_get_cpu_power() return 0 if the policy is NULL. Then in
em_create_perf_table(), the later zero check for power is not invalid
as power is uninitialized. As Lukasz suggested, it must return -EINVAL when
the 'policy' is not found. So return -EINVAL to fix it.
