In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through.
This patch fixes the following warnings: drivers/memstick/host/jmb38x_ms.c: In function ‘jmb38x_ms_write_data’: drivers/memstick/host/jmb38x_ms.c:261:15: warning: this statement may fall through [-Wimplicit-fallthrough=] host->io_pos++; ~~~~~~~~~~~~^~ drivers/memstick/host/jmb38x_ms.c:262:2: note: here case 2: ^~~~ drivers/memstick/host/jmb38x_ms.c:264:15: warning: this statement may fall through [-Wimplicit-fallthrough=] host->io_pos++; ~~~~~~~~~~~~^~ drivers/memstick/host/jmb38x_ms.c:265:2: note: here case 1: ^~~~ drivers/memstick/host/tifm_ms.c: In function ‘tifm_ms_write_data’: drivers/memstick/host/tifm_ms.c:168:15: warning: this statement may fall through [-Wimplicit-fallthrough=] host->io_pos++; ~~~~~~~~~~~~^~ drivers/memstick/host/tifm_ms.c:169:2: note: here case 2: ^~~~ drivers/memstick/host/tifm_ms.c:171:15: warning: this statement may fall through [-Wimplicit-fallthrough=] host->io_pos++; ~~~~~~~~~~~~^~ drivers/memstick/host/tifm_ms.c:172:2: note: here case 1: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
