[ Upstream commit c5dd28e7fb4f63475b50df4f58311df92939d011 ]
According to trigger_data_alloc() doc, trigger_data_free() should be used to free an event_trigger_data object. This fixes a mismatch introduced when kzalloc was replaced with trigger_data_alloc without updating the corresponding deallocation calls.
