This patch fixes the following warnings: drivers/watchdog/machzwd.c: In function ‘zf_set_timer’: ./arch/x86/include/asm/io.h:355:14: warning: this statement may fall through [-Wimplicit-fallthrough=] #define outw outw drivers/watchdog/machzwd.c:80:53: note: in expansion of macro ‘outw’ #define zf_writew(port, data) { outb(port, INDEX); outw(data, DATA_W); } ^~~~ drivers/watchdog/machzwd.c:179:3: note: in expansion of macro ‘zf_writew’ zf_writew(COUNTER_1, new); ^~~~~~~~~ drivers/watchdog/machzwd.c:180:2: note: here case WD2: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
