From e61555c29c28a4a3b6ba6207f4a0883ee236004d Mon Sep 17 00:00:00 2001 From: Jérémy Lefaure Date: Wed, 8 Mar 2017 20:18:09 -0500 Subject: EDAC, i5000, i5400: Fix use of MTR_DRAM_WIDTH macro MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The MTR_DRAM_WIDTH macro returns the data width. It is sometimes used as if it returned a boolean true if the width if 8. Fix the tests where MTR_DRAM_WIDTH is misused.
