Subject: cpufreq: s3c24xx: Fix broken s3c_cpufreq_init()

From: Viresh Kumar <[email protected]>

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.
