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 6 patches as they touch different subsystems and are maintained by different people. There is no functional change. V5: - drop 4 patches - change return value int topology.c suggested by Jonathan Cameron - fix code in processor_thermal.c suggested by Rafael and Jonathan Cameron - fix code in intel_pstate.c suggested by Rafael - fix code in governor_passive.c suggested Jonathan Cameron - fix code in energy_model.c suggested by Rafael and Krzysztof Kozlowski V4: - Fix compile error in topology.c - drop 2 patches - Move code into a function in processor_thermal.c - Move code into a function in intel_pstate.c - Move policy declare in dtpm_cpu.c - Fix compile error in imx_thermal.c - Fix compile error in ti-thermal-common.c - Fix compile error in energy_model.c V3: - drop patch 'KVM: x86: Use __free(put_cpufreq_policy) for policy reference' - removed 5 patches which has been applied - Consolidate CPUFreq policy assignments and allocations into one line, suggested by Ben Horgan - Change cpu_has_cpufreq() return type to bool, following Rafael's suggestion - Change the title to 'Use scope-based cleanup helper' V2: - Fix compile error in powernv-cpufreq.c - Split patch to separate logical changes Zihuan Zhang (6): arm64: topology: Use scope-based cleanup helper ACPI: processor: thermal: Use scope-based cleanup helper cpufreq: intel_pstate: Use scope-based cleanup helper PM / devfreq: Use scope-based cleanup helper drm/i915: Use scope-based cleanup helper PM: EM: Use scope-based cleanup helper arch/arm64/kernel/topology.c | 11 ++---- drivers/acpi/processor_thermal.c | 52 +++++++++++++------------ drivers/cpufreq/intel_pstate.c | 59 +++++++++++++++------------- drivers/devfreq/governor_passive.c | 60 +++++++++++------------------ drivers/gpu/drm/i915/gt/intel_llc.c | 4 +- kernel/power/energy_model.c | 9 +---- 6 files changed, 89 insertions(+), 106 deletions(-) -- 2.25.1
