From 4c4e45669de475573b15d968a6dca8d00124c9ad Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Mon, 23 Sep 2013 19:16:57 +0900 Subject: watchdog: kempld_wdt: Fix bit mask definition STAGE_CFG bits are defined as [5:4] bits. However, '(((x) & 0x30) << 4)' handles [9:8] bits. Thus, it should be fixed in order to handle [5:4] bits.
