From: "Gustavo A. R. Silva" <>

> 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=]
> drivers/net/ethernet/broadcom/cnic.c:4050:2: note: here
>   ^~~~
> 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.
