Subject: [PATCH 01/10] scsi: aacraid: Drop redundant pci_enable_pcie_error_reporting()
Date: Tue,  7 Mar 2023 12:28:33 -0600	[thread overview]
Message-ID: <20230307182842.870378-2-helgaas@kernel.org> (raw)
In-Reply-To: <20230307182842.870378-1-helgaas@kernel.org>

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.

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.

Also remove pci_disable_pcie_error_reporting() from the .error_detected()
path, which was added by 5c63f7f710bd ("aacraid: Added EEH support") but
looks unnecessary.  Error reporting will be disabled by the device reset
and will be re-enabled by the pci_restore_state() in aac_pci_slot_reset().
