Subject: watchdog: Fix fall-through warnings for Clang
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=18a0e8d0f103af40c82f751fabb0b4cb0bf2f32a;p=linux.git

watchdog: Fix fall-through warnings for Clang

In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning
by explicitly adding a fallthrough pseudo-keyword instead of letting the
code fall through to the next case.
