watchdog: sc1200: 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/sc1200wdt.c: In function ‘sc1200wdt_ioctl’:
drivers/watchdog/sc1200wdt.c:241:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
sc1200wdt_write_data(WDTO, timeout);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/watchdog/sc1200wdt.c:244:2: 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.
