The recent rename of event_hist_trigger_parse() caused smatch re-evaluation of trace_events_hist.c and as a result an old warning was found: kernel/trace/trace_events_hist.c:6174 event_hist_trigger_parse() error: we previously assumed 'glob' could be null (see line 6166) glob should never be null (and apparently smatch can also figure that out and skip the warning when using the cross-function DB (but which can't be used with a 0day build as it takes too much time to generate)). Nonetheless for clarity, remove the test but add a WARN_ON() in case the code ever changes.
