  10
  11 The missed break statement in the outer switch makes the code fall through
  12 always and thus always same value will be printed.
  13
  14 Besides that, compiler warns about missed fall through marker:
  15
  16 drivers/usb/dwc3/./trace.h: In function ‘trace_raw_output_dwc3_log_trb’:
  17 drivers/usb/dwc3/./trace.h:246:4: warning: this statement may fall through [-Wimplicit-fallthrough=]
  18     switch (pcm) {
  19     ^~~~~~
  20
  21 Add the missing break statement to work correctly without compilation
  22 warnings.
