Subject[PATCH RESEND] cpufreq: Use list_is_last() to check last entry of the policy list
Date
Currently next_policy() explicitly checks if a policy is the last
policy in the cpufreq_policy_list. Use the standard list_is_last
primitive instead.

The earlier version one was based on an Juri's experimental branch.
I have based this one on linux-pm.git linux-next branch.
