Subject: [PATCH] scsi: mptfusion: mark expected switch fall-throughs
Date: Tue, 3 Jul 2018 17:20:03 -0500	[thread overview]
Message-ID: <20180703222003.GA4593@embeddedor.com> (raw)

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

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