[PATCH] cpufreq: armada-8k: Fix off by one in armada_8k_cpufreq_free_table()
From: Dan Carpenter <hidden>

Also in:
kernel-janitors, linux-pm, lkml
Subsystem:
arm/marvell kirkwood and armada 370, 375, 38x, 39x, xp, 3700, 7k/8k, cn9130 soc support, cpu frequency scaling framework, the rest · Maintainers:
Andrew Lunn, Gregory Clement, Sebastian Hesselbarth, "Rafael J. Wysocki", Viresh Kumar, Linus Torvalds
The freq_tables[] array has num_possible_cpus() elements so, to avoid an
out of bounds access, this loop should be capped at "< nb_cpus" instead
of "<= nb_cpus". The freq_tables[] array is allocated in
armada_8k_cpufreq_init().
