Subject: [PATCH] watchdog: f71808e_wdt: mark expected switch fall-throughs
Message-ID: <20171102192817.GA20042@embeddedor.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
