[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Fix kernel-doc warnings in devfreq files.
Also fix a typo.

../include/linux/devfreq.h:181: warning: Function parameter or member 'last_status' not described in 'devfreq'

../drivers/devfreq/devfreq.c:1687: warning: bad line:         - Resource-managed devfreq_register_notifier()
../drivers/devfreq/devfreq.c:1723: warning: bad line:         - Resource-managed devfreq_unregister_notifier()
../drivers/devfreq/devfreq-event.c:355: warning: Function parameter or member 'edev' not described in 'devfreq_event_remove_edev'
../drivers/devfreq/devfreq-event.c:355: warning: Excess function parameter 'dev' description in 'devfreq_event_remove_edev'
