firewire: mark expected switch fall-throughs
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: drivers/firewire/core-device.c: In function ‘set_broadcast_channel’: drivers/firewire/core-device.c:969:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (data & cpu_to_be32(1 << 31)) { ^ drivers/firewire/core-device.c:974:3: note: here case RCODE_ADDRESS_ERROR: ^~~~ drivers/firewire/core-iso.c: In function ‘manage_channel’: drivers/firewire/core-iso.c:308:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if ((data[0] & bit) == (data[1] & bit)) ^ drivers/firewire/core-iso.c:312:3: note: here default: ^~~~~~~ drivers/firewire/core-topology.c: In function ‘count_ports’: drivers/firewire/core-topology.c:69:23: warning: this statement may fall through [-Wimplicit-fallthrough=] (*child_port_count)++; ~~~~~~~~~~~~~~~~~~~^~ drivers/firewire/core-topology.c:70:3: note: here case SELFID_PORT_PARENT: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that in some cases, the code comment is modified in accordance with what GCC is expecting to find. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Cc: Kees Cook <> Cc: Mathieu Malaterre <> Signed-off-by: Stefan Richter <> (reworded a comment) Signed-off-by: Gustavo A.
