[PATCH] watchdog: f71808e_wdt: mark expected switch fall-throughs
From: Gustavo A. R. Silva
Date: Thu Nov 02 2017 - 15:28:23 EST
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.
