scsi: mptscsih: 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/message/fusion/mptscsih.c: In function mptscsih_io_done : drivers/message/fusion/mptscsih.c:741:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if ( ioc->bus_type == SAS ) { ^ drivers/message/fusion/mptscsih.c:790:3: note: here case MPI_IOCSTATUS_SCSI_TASK_TERMINATED: /* 0x0048 */ ^~~~ drivers/message/fusion/mptscsih.c:884:4: warning: this statement may fall through [-Wimplicit-fallthrough=] scsi_set_resid(sc, 0); ^~~~~~~~~~~~~~~~~~~~~ drivers/message/fusion/mptscsih.c:885:3: note: here case MPI_IOCSTATUS_SCSI_RECOVERED_ERROR: /* 0x0040 */ ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
