Subject: [PATCH 05/41] scsi: aic7xxx: aic79xx: mark expected switch fall-through
Date: Tue, 27 Nov 2018 22:26:19 -0600	[thread overview]
Message-ID: <ff0ea78271abe136badebfbeba1d4373fb836bce.1543374820.git.gustavo@embeddedor.com> (raw)
In-Reply-To: <cover.1543374820.git.gustavo@embeddedor.com>

In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.

Notice that, in some cases, I replaced "FALLTHROUGH" with a "fall through"
annotation and then placed it at the bottom of the corresponding switch
case, which is what GCC is expecting to find.
