Subject: [PATCH 3/8] EDAC: amd64: Use static attribute groups
Instead of calling device_create_file() and device_remove_file()
manually, pass the static attribute groups with the new
edac_mc_add_mc_with_groups(). The conditional creation of inject
sysfs files is done by a proper is_visible callback.
