Subject: watchdog: watchdog_dev: mark expected switch fall-through
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e2af3092d05a814d670a045df983fcefb18e7c14;p=linux.git

watchdog: watchdog_dev: mark expected switch fall-through

In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.

Notice that in this particular case I replaced "Fall" with a proper
"fall through" comment, which is what GCC is expecting to find.
