Subject: [PATCH] watchdog: w83977f_wdt: Mark expected switch fall-through
Date: Tue, 27 Mar 2018 14:30:41 -0500 [thread overview]
Message-ID: <20180327193041.GA2432@embeddedgus> (raw)
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.
