| |
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/misc/sgi-xp/xpc_uv.c: In function ‘xpc_handle_activate_mq_msg_uv’: drivers/misc/sgi-xp/xpc_uv.c:573:3: warning: this statement may fall through [-Wimplicit-fallthrough=] xpc_wakeup_channel_mgr(part); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/misc/sgi-xp/xpc_uv.c:575:2: note: here case XPC_ACTIVATE_MQ_MSG_MARK_ENGAGED_UV: ^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
