Subject: [PATCH v2 00/18] cpufreq: use __free() for all cpufreq_cpu_get() references
This patchset converts all remaining cpufreq users to rely on the
__free(put_cpufreq_policy) annotation for policy references, instead of
calling cpufreq_cpu_put() manually.
Motivation:
- Reduce the chance of reference counting mistakes
- Make the code more consistent with the latest kernel style
- behavior remains the same, but reference counting is now safer
and easier to maintain.
The changes are split into 18 patches as they touch different subsystems
and are maintained by different people. There is no functional change.
V2:
- Fix compile error in powernv-cpufreq.c
- Split patch to separate logical changes
