watchdog: w83877f_wdt: Mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/watchdog/w83877f_wdt.c: In function ‘fop_ioctl’: drivers/watchdog/w83877f_wdt.c:294:3: warning: this statement may fall through [-Wimplicit-fallthrough=] wdt_keepalive(); ^~~~~~~~~~~~~~~ drivers/watchdog/w83877f_wdt.c:297:2: note: here case WDIOC_GETTIMEOUT: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R.
