Subject: [PATCH] nvme-pci: drop redundant pci_enable_pcie_error_reporting()
Date: Tue, 7 Mar 2023 14:32:43 -0600 [thread overview]
Message-ID: <20230307203243.882202-1-helgaas@kernel.org> (raw)
From: Bjorn Helgaas <bhelgaas@google.com>
pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages. Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration, so the
driver doesn't need to do it itself.
Remove the redundant pci_enable_pcie_error_reporting() call from the
driver. Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.
Note that this only controls ERR_* Messages from the device. An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.
