Subject: [PATCH 28/41] scsi: lpfc: lpfc_sli: Mark expected switch fall-throughs
Date: Tue, 27 Nov 2018 22:32:18 -0600	[thread overview]
Message-ID: <cb80d182329a02971ff365446b0e04771fc77da8.1543374820.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 this particular case, I replaced "Drop thru" and
"Fall Thru" with "fall through" annotations, which is what GCC
is expecting to find.

Also, in some cases a dash is added as a token in order to separate
the "fall through" annotation from the rest of the comment on the
same line, which is what GCC is expecting to find.

Addresses-Coverity-ID: 114979 ("Missing break in switch")
