Hi, Sergey

Currently other vendor drivers do not clear error status in their own 
init code, I don't exactly know what is special reason for clearing 
error status during init code in ntb driver.


An evidence is in pci_aer_init(), PCI core driver has do 
pci_aer_clear_status() and pci_enable_pcie_error_reporting() in common 
process. So vendor drivers don't need to do again.


But I don't know the reason why many vendor drivers reserve 
pci_enable_pcie_error_reporting() after commit f26e58bf6f54 ("PCI/AER: 
Enable error reporting when AER is native"). Do they need to be removed?

Could Bjorn and Sathyanarayanan help look into it, thanks a lot.

Thanks.
