Silva" Date: Thu, 5 Jul 2018 09:56:00 -0500 Subject: PCI: Mark fall-through switch cases before enabling -Wimplicit-fallthrough In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Warning level 2 was used: -Wimplicit-fallthrough=2 Signed-off-by: Gustavo A. R.
