Is there any chance to pull those corrected patches to v3.12?

After your comments I think, that this code could be rewritten:
list_for_each_entry(policy, &cpufreq_policy_list, policy_list) {
freq_table = cpufreq_frequency_get_table(policy->cpu);
if (freq_table) {
ret = cpufreq_frequency_table_cpuinfo(policy,
freq_table);
if (ret) {
pr_err("%s: Policy frequency update
failed\n")
break;
}
policy->user_policy.max = policy->max;
__cpufreq_governor(policy,CPUFREQ_GOV_LIMITS);
}
}
return ret;
}
