The patch ec5ce098: "tracing: Allow whitespace to surround hist trigger filter" from Jan 15, 2018, leads to the following Smatch static checker warning: kernel/trace/trace_events_hist.c:6199 event_hist_trigger_parse() warn: 'p' can't be NULL. Since p is always checked for a NULL value at the top of loop and nothing in the rest of the loop will set it to NULL, the warning is correct and might as well be 1 to silence the warning.
