Subject: [PATCH 30/30] amd64_edac: Enable driver on F15h
From: Borislav Petkov <borislav.petkov@....com>
Add the PCI device ids required for driver registration. Remove
pvt->ctl_name and use the family descriptor directly, instead. Then,
bump driver version and fixup its format. Finally, enable DRAM ECC
decoding on F15h.
