net/mlx4: Mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/net/ethernet/mellanox/mlx4/eq.c: In function ‘mlx4_eq_int’: drivers/net/ethernet/mellanox/mlx4/mlx4.h:219:5: warning: this statement may fall through [-Wimplicit-fallthrough=] if (mlx4_debug_level) \ ^ drivers/net/ethernet/mellanox/mlx4/eq.c:558:4: note: in expansion of macro ‘mlx4_dbg’ mlx4_dbg(dev, "%s: MLX4_EVENT_TYPE_SRQ_LIMIT. srq_no=0x%x, eq 0x%x\n", ^~~~~~~~ drivers/net/ethernet/mellanox/mlx4/eq.c:561:3: note: here case MLX4_EVENT_TYPE_SRQ_CATAS_ERROR: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enabling -Wimplicit-fallthrough.
