Subject: watchdog: kempld-wdt: Use the correct value when configuring the
prescaler with the watchdog
From: gundberg <[email protected]>
commit a9e0436b303e94ba57d3bd4b1fcbeaa744b7ebeb upstream.
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.
