[RFC PATCH 1/1] watchdog: fix watchdog_nmi_enable_all()

From: Ulrich Obergfell
Date: Fri Apr 17 2015 - 05:25:01 EST


The 'watchdog_user_enabled' variable is only used as an 'interface'
to the /proc/sys/kernel/watchdog parameter. The actual state of the
watchdog is tracked by bits in the 'watchdog_enabled' variable. So,
watchdog_nmi_enable_all() should check the NMI_WATCHDOG_ENABLED bit
in 'watchdog_enabled'.
