From 36d050d913333ea21e9728cbbc1fc07ae5be8d6c Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Tue, 23 Aug 2016 21:46:06 +1000 Subject: [PATCH] m68knommu: fix IO write size in nettel pin set The pin write code that supports the UART signals is not using he correct word write IO access method. It correctly reads the correct 16 bit registrer, it should also write the new value back with a 16 bit write. Fix it to use writew().
