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.
