Input: libps2 - mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/input/serio/libps2.c: In function ‘ps2_handle_ack’: drivers/input/serio/libps2.c:407:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (ps2dev->flags & PS2_FLAG_NAK) { ^ drivers/input/serio/libps2.c:417:2: note: here case 0x00: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
