[PATCH] watchdog: kempld-wdt: Use the correct value when configuring the prescaler with the watchdog

From: gundberg
Date: Thu Apr 24 2014 - 09:50:42 EST


Use the prescaler index, rather than its value, to configure the watchdog.
This will prevent a mismatch with the prescaler used to calculate the cycles.
