From d3ed411123c9655c6013cb8ed8d3d91cc2dc8c62 Mon Sep 17 00:00:00 2001 From: Rudolf Marek Date: Sat, 4 May 2013 00:08:34 +0200 Subject: AMD Trinity boards: Use `sizeof(var)` to get its size MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Change `sizeof(type) * n`, where n is the number of array elements, to `sizeof(variable)` to directly get the size of the variable (struct, array). Determining the size by counting array elements is error prone and unnecessary. Not sure why the copy is needed instead of direct reference. Maybe it has something to do with CAR? These changes are based on Rudolf’s original patch »ASUS F2A85-M: Correct and clean up PCIe config« [1], where it was just done for the ASUS board.
