From 5a5d237169152d4d7e4b6105eab15831829fb8e7 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Mon, 17 Jan 2011 17:52:57 +0100 Subject: [PATCH] amd64_edac: Sanitize ->read_dram_ctl_register This function is relevant for F10h and higher, and it has only one callsite so drop its function pointer from the low_ops struct.
