H A D | cpuidle.c | c998c078 Tue Apr 05 14:05:38 CDT 2016 Dave Gerlach <d-gerlach@ti.com> cpuidle: Indicate when a device has been unregistered
Currently the 'registered' member of the cpuidle_device struct is set to 1 during cpuidle_register_device. In this same function there are checks to see if the device is already registered to prevent duplicate calls to register the device, but this value is never set to 0 even on unregister of the device. Because of this, any attempt to call cpuidle_register_device after a call to cpuidle_unregister_device will fail which shouldn't be the case.
To prevent this, set registered to 0 when the device is unregistered.
