Re: [PATCH] watchdog: pcwd_pci: mark expected switch fall-through

Hi Wim,

Quoting Wim Van Sebroeck <wim@xxxxxxxxx>:

Hi Gustavo,

In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.

Notice that in this particular case I replaced "Fall" with a proper
"fall through" comment, which is what GCC is expecting to find.

Shouldn't the /* fall through */ come after the } ?


Yep, you are right.

I'll fix that.

Thank you!
