[PATCH 1/2] acpi-cpufreq: make the freq_table store the same freq value
From: Wang Weidong
Date: Thu Nov 27 2014 - 21:44:01 EST
As the initialized freq_tables maybe different from the p-states
values, so the array index is different as well.
Although in this case:
p-states value: [2400 2400 2000 ...], while the freq_tables:
[2400 2000 ... CPUFREQ_TABLE_END]. After setted the freqs 2000,
the perf->state is 3 while the freqs_table's index should be 2.
So when call the get_cur_freq_on_cpu, the freqs value we get
is 2400.
So, make the freq_table store the same value as well.
