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.
