GCC9 is confused by this comment when building with CFLAG -Wimplicit-fallthrough=2: vl.c: In function ‘qemu_ref_timedate’: vl.c:773:15: error: this statement may fall through [-Werror=implicit-fallthrough=] 773 | value -= rtc_realtime_clock_offset; | ~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~ vl.c:775:5: note: here 775 | case QEMU_CLOCK_VIRTUAL: | ^~~~ cc1: all warnings being treated as errors Rewrite the comment using 'fall through' which is recognized by GCC and static analyzers.
