5.4-stable review patch. If anyone has any objections, please let me know.

From: Dan Carpenter dan.carpenter@linaro.org
commit 4a26df233266a628157d7f0285451d8655defdfc upstream.
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().
