From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx> The fix for an AMD POGO erratum related to SHPC incorrectly identified the device. The workaround should be applied only for AMD POGO devices, but it was instead applied to: - all AMD bridges, and - all devices from any vendor with device ID 0x7458 Fixes: 53044f357448 ("[PATCH] PCI Hotplug: shpchp: AMD POGO errata fix") Signed-off-by: Bjorn Helgaas <bhelgaas@xxxxxxxxxx> --- drivers/pci/hotplug/shpchp_ctrl.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/pci/hotplug/shpchp_ctrl.c b/drivers/pci/hotplug/shpchp_ctrl.c index bedda5bda910..1047b56e5730 100644 --- a/drivers/pci/hotplug/shpchp_ctrl.c +++ b/drivers/pci/hotplug/shpchp_ctrl.c @@ -585,13 +585,13 @@ static int shpchp_enable_slot (struct slot *p_slot) ctrl_dbg(ctrl, "%s: p_slot->pwr_save %x\n", __func__, p_slot->pwr_save); p_slot->hpc_ops->get_latch_status(p_slot, &getstatus); - if (((p_slot->ctrl->pci_dev->vendor == PCI_VENDOR_ID_AMD) || - (p_slot->ctrl->pci_dev->device == PCI_DEVICE_ID_AMD_POGO_7458)) + if ((p_slot->ctrl->pci_dev->vendor == PCI_VENDOR_ID_AMD && + p_slot->ctrl->pci_dev->device == PCI_DEVICE_ID_AMD_POGO_7458) && p_slot->ctrl->num_slots == 1) { - /* handle amd pogo errata; this must be done before enable */ + /* handle AMD POGO errata; this must be done before enable */ amd_pogo_errata_save_misc_reg(p_slot); retval = board_added(p_slot); - /* handle amd pogo errata; this must be done after enable */ + /* handle AMD POGO errata; this must be done after enable */ amd_pogo_errata_restore_misc_reg(p_slot); } else retval = board_added(p_slot);
