[Qemu-devel] [PULL 12/14] spapr_events: Rewrite a fall through comment

[Laurent Vivier]

From: Philippe Mathieu-Daudé <address@hidden>

GCC9 is confused by this comment when building with CFLAG
-Wimplicit-fallthrough=2:

    CC      ppc64-softmmu/hw/ppc/spapr_rtc.o
  hw/ppc/spapr_events.c: In function ‘rtas_event_log_to_source’:
  hw/ppc/spapr_events.c:312:12: error: this statement may fall through 
[-Werror=implicit-fallthrough=]
    312 |         if (spapr_ovec_test(spapr->ov5_cas, OV5_HP_EVT)) {
        |            ^
  hw/ppc/spapr_events.c:317:5: note: here
    317 |     case RTAS_LOG_TYPE_EPOW:
        |     ^~~~
  cc1: all warnings being treated as errors

Rewrite the comment using 'fall through' which is recognized by
GCC and static analyzers.
