R. Silva" , Kees Cook List-Id: linux-scsi@vger.kernel.org In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/message/fusion/mptbase.c: In function ‘mptbase_reply’: drivers/message/fusion/mptbase.c:643:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (event != MPI_EVENT_EVENT_CHANGE) ^ drivers/message/fusion/mptbase.c:646:2: note: here case MPI_FUNCTION_CONFIG: ^~~~ 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. Signed-off-by: Gustavo A. R.
