Subject: [PATCH 4.9 045/218] hwmon: (sch56xx-common) Replace WDOG_ACTIVE with WDOG_HW_RUNNING
From: Armin Wolf <W_Armin@....de>
[ Upstream commit 647d6f09bea7dacf4cdb6d4ea7e3051883955297 ]
If the watchdog was already enabled by the BIOS after booting, the
watchdog infrastructure needs to regularly send keepalives to
prevent a unexpected reset.
WDOG_ACTIVE only serves as an status indicator for userspace,
we want to use WDOG_HW_RUNNING instead.
Since my Fujitsu Esprimo P720 does not support the watchdog,
this change is compile-tested only.
