PCI based device drivers handles ERR_NONFATAL  by registering
pci_error_handlers. some of the drivers clear AER uncorrectable status
in slot_reset while some in resume.
Drivers should not have responsibility of clearing the AER status, instead 
shall be done by error and recovery framework defined in err.c


Agreed, and Keith's patch 43c9a34fe04e ("PCI/ERR: Always use the first
downstream port") [1], which is queued on pci/hotplug for v4.20, does
call pci_cleanup_aer_uncorrect_error_status() at the end of
pcie_do_recovery().

1) Does that seem like the right place?

2) I guess all we need now would be to remove the calls from the
   drivers?

3) If we remove all the calls from the drivers, we should remove the
   declaration from include/linux/aer.h, too.

I can take care of these updates if we agree they're the right thing
to do.
sure Bjorn. this patch already removes all the calls from drivers and adds 
call to pci_cleanup_aer_uncorrect_error_status().

Please feel free to modify or adapt and take care.

Regards,
Oza.

Clear the status while resuming, after reset_link was successful.
