Subject: cpufreq: fix bug in duplicate freq elimination code in acpi-cpufreq
From: Alexey Starikovskiy <alexey.y.starikovskiy@xxxxxxxxx>
Due to duplicate state elimiation in the loop earlier, the number of
valid_states can be less than perf->state_count, in which case freq_table
was ending up with some garbage/uninitialized entries in the table.
