Silva" Date: Tue, 7 May 2019 09:23:00 -0500 Subject: [PATCH] nvme-pci: mark expected switch fall-through MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/nvme/host/pci.c: In function ‘nvme_timeout’: drivers/nvme/host/pci.c:1298:12: warning: this statement may fall through [-Wimplicit-fallthrough=] shutdown = true; ~~~~~~~~~^~~~~~ drivers/nvme/host/pci.c:1299:2: note: here case NVME_CTRL_CONNECTING: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
