Input: db9 - 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/joystick/db9.c: In function ‘db9_saturn_read_packet’: drivers/input/joystick/db9.c:256:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (tmp == 0xff) { ^ drivers/input/joystick/db9.c:263:2: note: here default: ^~~~~~~ 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. Silva <gustavo@embeddedor.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
