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()
