Subject: [PATCH] PCI: Mark expected switch fall-throughs
Date: Thu, 5 Jul 2018 09:56:00 -0500 [thread overview]
Message-ID: <20180705145600.GA22099@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
