This patch fixes the following warning: drivers/net/dsa/microchip/ksz9477.c: In function ‘ksz9477_get_interface’: drivers/net/dsa/microchip/ksz9477.c:1145:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (gbit) ^ drivers/net/dsa/microchip/ksz9477.c:1147:2: note: here case 0: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
