Subject: [PATCH v2 1/1] watchdog: sp805: disable watchdog on remove
Date: Thu, 14 Apr 2022 05:42:33 +0000	[thread overview]
Message-ID: <20220414054233.1357-2-farbere@amazon.com> (raw)
In-Reply-To: <20220414054233.1357-1-farbere@amazon.com>

Disable the watchdog if it is active while removing the module.
It is necessary in order to prevent a reset in case watchdog
hw was running before the removal.
