PM / OPP: add missing of_node_put() for of_get_cpu_node()

2017-10-13T22:49:41+00:00

Commit 762792913f8c (PM / OPP: Fix get sharing CPUs when hotplug is used) moved away from using cpu_dev->of_node because of some limitations. However, commit 7467c9d95989 (of: return of_get_cpu_node from of_cpu_device_node_get if CPUs are not registered) added support to fall back to of_get_cpu_node() if called if CPUs are not registered yet. Add the missing of_node_put() for the CPU device nodes. Also go back to using of_cpu_device_node_get() in dev_pm_opp_of_get_sharing_cpus() to avoid scanning the device tree again.

PM / OPP: Add missing of_node_put(np)

2017-10-10T23:53:22+00:00

The for_each_available_child_of_node() loop in _of_add_opp_table_v2() doesn't drop the reference to "np" on errors. Fix that.

PM / OPP: Move the OPP directory out of power/

2017-10-03T00:45:12+00:00

The drivers/base/power/ directory is special and contains code related to power management core like system suspend/resume, hibernation, etc. It was fine to keep the OPP code inside it when we had just one file for it, but it is growing now and already has a directory for itself. Lets move it directly under drivers/ directory, just like cpufreq and cpuidle. Signed-off-by: Viresh Kumar Acked-by: Stephen Boyd Signed-off-by: Rafael J. Wysocki
