Revision 5a7e56a5d29071bcccd947dee6e3b9f8e4eb3309 authored by Viresh Kumar on 04 March 2014, 03:44:00 UTC, committed by Rafael J. Wysocki on 06 March 2014, 12:25:29 UTC
Policy must be fully initialized before it is being made available for use by others. Otherwise cpufreq_cpu_get() would be able to grab a half initialized policy structure that might not have affected_cpus (for example) populated. Then, anybody accessing those fields will get a wrong value and that will lead to unpredictable results. In order to fix this, do all the necessary initialization before we make the policy structure available via cpufreq_cpu_get(). That will guarantee that any code accessing fields of the policy will get correct data from them.
