Silva" Date: Mon, 20 May 2019 09:51:05 -0500 Subject: vlan: Mark expected switch fall-through MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 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: net/8021q/vlan_dev.c: In function ‘vlan_dev_ioctl’: net/8021q/vlan_dev.c:374:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (!net_eq(dev_net(dev), &init_net)) ^ net/8021q/vlan_dev.c:376:2: note: here case SIOCGMIIPHY: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
