Wysocki Change cpufreq_policy_alloc() to take a CPU number instead of a CPU device pointer as its argument, as it is the only function called by cpufreq_add_dev() taking a device pointer argument at this point. That will allow us to split the CPU online part from cpufreq_add_dev() more cleanly going forward. Signed-off-by: Rafael J.
