Subject: [PATCH 20/28] net: txgbe: Drop redundant pci_enable_pcie_error_reporting()

From: Bjorn Helgaas <bhelgaas@...gle.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.
