[PATCH 04/28] bnx2x: Drop redundant pci_enable_pcie_error_reporting()

From: Bjorn Helgaas
Date: Tue Mar 07 2023 - 13:25:16 EST


From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

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.
