Subject: [PATCH] video: fbdev: cirrusfb: mark expected switch fall-throughs
Date: Mon, 6 Nov 2017 16:45:50 -0600	[thread overview]
Message-ID: <20171106224550.GA2583@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 placed the "fall through" comment
on its own line, which is what GCC is expecting to find.
