Subject: [PATCH 12/12] watchdog: Set the preaction fields for drivers supporting pretimeout
Date: Mon, 19 Aug 2019 15:37:11 -0500
Message-ID: <20190819203711.32599-13-minyard@acm.org> (raw)
In-Reply-To: <20190819203711.32599-1-minyard@acm.org>

From: Corey Minyard <cminyard@mvista.com>

None can be changed, so no need for the set operation.  The only
one not done was kempld_wdt.c; I couldn't figure out how the
pretimeout worked in that one.
