+Subject: [PATCH 2/6] OMAP2+: cpufreq: handle invalid cpufreq table
+
+Handle the case when cpufreq_frequency_table_cpuinfo fails. freq_table
+that we passed failed the internal test of cpufreq generic driver,
+so we should'nt be using the freq_table as such. Instead, warn and
+fallback to clock functions for validation and operation.
