Subject: hpwdt: Fix kdump issue in hpwdt
From: Toshi Kani <toshi.k...@hp.com>
commit 308b135e4fcc00c80c07e0e04e7afa8edf78583c upstream.
kdump can be interrupted by watchdog timer when the timer is left
activated on the crash kernel. Changed the hpwdt driver to disable
watchdog timer at boot-time. This assures that watchdog timer is
disabled until /dev/watchdog is opened, and prevents watchdog timer
to be left running on the crash kernel.
