From: Chen Qun <[email protected]> When using -Wimplicit-fallthrough in our CFLAGS, the compiler showed warning: hw/ppc/ppc.c: In function ‘ppc6xx_set_irq’: hw/ppc/ppc.c:118:16: warning: this statement may fall through [-Wimplicit-fallthrough=] 118 | if (level) { | ^ hw/ppc/ppc.c:123:9: note: here 123 | case PPC6xx_INPUT_INT: | ^~~~
According to the discussion, a break statement needs to be added here.
