Bradley Pankow	827108d080	amdgpu: fix NULL pointer dereference at tonga_check_states_equal ... The event_data passed from pem_fini was not cleared upon initialization. This caused NULL checks to pass and cast_const_phw_tonga_power_state to attempt to dereference an invalid pointer. Clear the event_data in pem_init and pem_fini before calling pem_handle_event.
