From 1c1b2434017206b612764fad1820b6dd48cb9e92 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Wed, 19 Jul 2017 10:27:53 +0200 Subject: [PATCH] watchdog: renesas_wdt: don't round closest with get_timeleft We should never return more time left than there actually is. So, switch to a plain divider instead of DIV_ROUND_CLOSEST.
