PM: Lock PM device list mutex in show_dev_hash()
Lock the PM device list mutex using device_pm_lock() and device_pm_unlock() around the list iteration in show_dev_hash(). show_dev_hash() was reverse iterating dpm_list without first locking the mutex that the functions in drivers/base/power/main.c lock. I assume this was unintentional since there is no comment suggesting why the lock might not be necessary. Signed-off-by: James Hogan <james@albanarts.com> Signed-off-by: Rafael J.
