For function _base_get_event_diag_triggers(), it has a return
value, but the description of the comment information is
incorrect. In addition, in the abnormal process, 0 should
not be returned, 0 means success, here an abnormal value
needs to be return, In order to retry after an exception
occurs, the setting returns to -EAGAIN, from code analysis,
it will not cause infinite retries.
