From 395ae783b384e5243804b07fba3e3f8379ddf1d6 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Fri, 1 Oct 2010 18:38:19 +0200 Subject: amd64_edac: Add per-family init function Run a per-family init function which does all the settings based on the family this driver instance is running on. Move the scrubrate calculation in it and simplify code.
