Subject: [PATCH v2 6/9] watchdog: keembay: Removed timeout update in the TO ISR
Date: Mon, 17 May 2021 23:19:50 +0530	[thread overview]
Message-ID: <20210517174953.19404-7-shruthi.sanil@intel.com> (raw)
In-Reply-To: <20210517174953.19404-1-shruthi.sanil@intel.com>

From: Shruthi Sanil <shruthi.sanil@intel.com>

In the TO ISR removed updating the Timeout value because
its not serving any purpose as the timer would have already expired
and the system would be rebooting.

Fixes: fa0f8d51e90d ("watchdog: Add watchdog driver for Intel Keembay Soc")
