Subject: watchdog: wdt_pci: mark expected switch fall-through
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=57b6d481f7a59c091b53a18c843d8631fa04f7eb;p=linux.git

watchdog: wdt_pci: mark expected switch fall-through

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.
