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

------------------

From: Viresh Kumar <viresh.ku...@linaro.org>

commit 0373ca74831b0f93cd4cdbf7ad3aec3c33a479a5 upstream.

commit a307a1e6bc0d "cpufreq: s3c: use cpufreq_generic_init()"
accidentally broke cpufreq on s3c2410 and s3c2412.

These two platforms don't have a CPU frequency table and used to skip
calling cpufreq_table_validate_and_show() for them.  But with the
above commit, we started calling it unconditionally and that will
eventually fail as the frequency table pointer is NULL.

Fix this by calling cpufreq_table_validate_and_show() conditionally
again.
