Dan Carpenter reported that:

 The patch a955d7ea: "trace: Add timerlat tracer" from Jun 22,
 2021, leads to the following static checker warning:

	kernel/trace/trace_osnoise.c:1400 timerlat_main()
	warn: inconsistent indenting

here:
  1389          while (!kthread_should_stop()) {
  1390                  now = ktime_to_ns(hrtimer_cb_get_time(&tlat->timer));
  1391                  diff = now - tlat->abs_period;
  1392
  1393                  s.seqnum = tlat->count;
  1394                  s.timer_latency = diff;
  1395                  s.context = THREAD_CONTEXT;
  1396
  1397                  trace_timerlat_sample(&s);
  1398
  1399  #ifdef CONFIG_STACKTRACE
  1400          if (osnoise_data.print_stack)
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
	    This should be indented another tab?

  1401                  if (osnoise_data.print_stack <= time_to_us(diff))
  1402                          timerlat_dump_stack();
  1403  #endif /* CONFIG_STACKTRACE */
  1404
  1405                  tlat->tracing_thread = false;
  1406                  if (osnoise_data.stop_tracing_total)
  1407                          if (time_to_us(diff) >= osnoise_data.stop_tracing_total)
  1408                                  osnoise_stop_tracing();
  1409
  1410                  wait_next_period(tlat);
  1411          }

And the static checker is right. Fix the indentation.
