From 4c7f4426c454f5787154b86406188d90d4c1b267 Mon Sep 17 00:00:00 2001 From: Michal Privoznik Date: Thu, 7 Sep 2017 10:05:25 +0200 Subject: [PATCH] watchdog.h: Drop local redefinition of actions enum We already have enum that enumerates all the actions that a watchdog can take when hitting its timeout: WatchdogAction. Use that instead of inventing our own. Signed-off-by: Michal Privoznik Message-Id: Reviewed-by: Eric Blake Reviewed-by: Markus Armbruster Reviewed-by: Daniel P.
