    Input: db9 - mark expected switch fall-through · 4e116e93
    Gustavo A. R. Silva authored
    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.
