From c6904ddb976d99b77d91b78a0ce5bdfffb416c49 Mon Sep 17 00:00:00 2001 From: Wim Van Sebroeck Date: Wed, 19 Nov 2008 20:02:02 +0000 Subject: [PATCH] [WATCHDOG] iTCO_wdt : correct status clearing The iTCO_wdt code was not clearing the correct bits. It now clears the timeout status bit and then the SECOND_TO_STS bit and then the BOOT_STS bit. Note: we should first clear the SECOND_TO_STS bit before clearing the BOOT_STS bit.
