Merge branch 'pci/err'
- Recognize disconnected devices so we don't bother trying to set them to "frozen" or "normal" state (Christoph Hellwig) - Clear PCI Status register during enumeration in case firmware left errors logged (Kai-Heng Feng) - Configure ECRC for every device, including hot-added ones (Stefan Roese) - Keep AER error reporting enabled for switches (Stefan Roese) - Enable error reporting for all devices that support AER (Stefan Roese) - Iterate over error counters instead of error strings to avoid printing junk in AER sysfs counters (Mohamed Khalfella) * pci/err: PCI/AER: Iterate over error counters instead of error strings PCI/AER: Enable error reporting when AER is native PCI/portdrv: Don't disable AER reporting in get_port_device_capability() PCI/AER: Configure ECRC for every device PCI: Clear PCI_STATUS when setting up device PCI/ERR: Recognize disconnected devices in report_error_detected()
