Subject: [PATCH] watchdog: iTCO_wdt: Fix detection of SMI-off case
Date: Mon, 26 Jul 2021 13:46:13 +0200 [thread overview]
Message-ID: <d84f8e06-f646-8b43-d063-fb11f4827044@siemens.com> (raw)
From: Jan Kiszka <jan.kiszka@siemens.com>
Obviously, the test needs to run against the register content, not its
address.
Fixes: cb011044e34c ("watchdog: iTCO_wdt: Account for rebooting on second timeout")
Reported-by: Mantas Mikulėnas <grawity@gmail.com>
