[PATCH 6.1 137/196] ice: Remove redundant pci_enable_pcie_error_reporting()

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Subsystem: intel ethernet drivers, networking drivers, the rest · Maintainers: Tony Nguyen, Przemek Kitszel, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

6.1-stable review patch.  If anyone has any objections, please let me know.

From: Bjorn Helgaas <bhelgaas@google.com>

[ Upstream commit ba153552c18d7eb839ec0bad7d7484e29ba4719c ]

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.

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 doesn't control interrupt generation by the Root Port; that
is controlled by the AER Root Error Command register, which is managed by
the AER service driver.
