[PATCH 03/11] cpufreq: fix kobject reference count handling

[Greg Kroah-Hartman]

From: Balaji Rao <balajirrao@xxxxxxxxx>

The cpufreq core should not take an extra kobject reference count for no
reason, and then refuse to release it.  This has been reported as
keeping machines from properly powering down all the way.
