commit 7b4bd871faa5f10317a53716cbe6b73ce6d970c6 Author: Rudolf Marek r.marek@assembler.cz Date: Sat May 4 00:08:34 2013 +0200
AMD Trinity boards: Use `sizeof(var)` to get its size
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.
