    xen-netfront: mark expected switch fall-through · 98105e9a
    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/net/xen-netfront.c: In function ‘netback_changed’:
    drivers/net/xen-netfront.c:2038:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
       if (dev->state == XenbusStateClosed)
          ^
    drivers/net/xen-netfront.c:2041:2: note: here
      case XenbusStateClosing:
      ^~~~
    
    Warning level 3 was used: -Wimplicit-fallthrough=3
    
    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.
