Subject: [PATCH v2] watchdog: pcwd_pci: mark expected switch fall-through
Date: Fri, 3 Nov 2017 11:02:30 -0500	[thread overview]
Message-ID: <20171103160230.GA9298@embeddedor.com> (raw)
In-Reply-To: <20171103104737.Horde.jIupkyXRbKxDR--eHgm0-aF@gator4166.hostgator.com>

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.

Signed-off-by: Gustavo A. R. Silva <garsilva@embeddedor.com>

Changes in v2:
 Place the "fall through" comment outside the unconditional code block.
