Summary: [wbwd][patch] Stop watchdog timer in attach routine if
it is already started
Product: Base System
Version: 10.2-STABLE

Patch to fix the issue.
According to comments in wbwd.c, the wbwd watchdog timer may be started before
the wbwd driver is attaching.
If so, watchdogd(8) must be started to prevent unnecessary reboot before the
watchdog fires, even if the machine is booting directly to single user mode.
Attached patch works around this. When the timer is already started, then
attach routine stops it.
Please someone fix the issue. Thanks.
