| |
In preparation to enabling -Wimplicit-fallthrough, refactor code a bit and mark switch cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/net/ethernet/broadcom/cnic.c: In function ‘cnic_cm_process_kcqe’: drivers/net/ethernet/broadcom/cnic.c:4044:11: warning: this statement may fall through [-Wimplicit-fallthrough=] opcode = L4_KCQE_OPCODE_VALUE_CLOSE_COMP; drivers/net/ethernet/broadcom/cnic.c:4050:2: note: here case L4_KCQE_OPCODE_VALUE_RESET_RECEIVED: ^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
Notice that, in this particular case, 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.
