Subject: [PATCH] kdb: kdb_keyboard: mark expected switch fall-throughs
Date: Sat, 4 Aug 2018 23:18:25 -0500	[thread overview]
Message-ID: <20180805041825.GA20310@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 the code comments with
a proper "fall through" annotation, which is what GCC is expecting
to find.
