So you are trying to figure if the frequency is listed in freq-table or not,
otherwise setting the frequency to a value you think is appropriate. Right ?

This is what the cpufreq core already does when it printed these boot time
messages. Do we really need to add this much code in here ?

If you really don't want to see the warning, how about fixing it the way cpufreq
core does ? i.e. with this call:

ret = __cpufreq_driver_target(policy, policy->cur - 1, CPUFREQ_RELATION_L);
