Subject: [PATCH] Smack: Mark expected switch fall-through
Date: Wed, 1 Aug 2018 17:38:54 -0500	[thread overview]
Message-ID: <20180801223854.GA14499@embeddedor.com> (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 "No break" with a
proper "Fall through" annotation, which is what GCC is expecting
to find.

Warning level 2 was used: -Wimplicit-fallthrough=2

Addresses-Coverity-ID: 115051 ("Missing break in switch")
