[PATCH 0/4] Expose PCIe AER stats via sysfs

[Rajat Jain]

This is a follow up to:
https://lkml.org/lkml/2018/5/22/1057

Respinning as a new patchset because the old one has been refactored
to include new patches (that were not part of original), and dropping
some patches. The major changes are:

* Provide breakdown of Fatal / non fatal errors separately
* Include the "total" in the same file
* do some PCI cleanup before the actual aer_stats stuff
* Include documentation in the main patch
* Rename variables / attributes to better match the newer reality.

Rajat Jain (4):
  PCI: Move pci_aer_init() and pci_no_aer() declarations to
    drivers/pci/pci.h
  PCI/AER: Define and allocate aer_stats structure for AER capable
    devices
  PCI/AER: Add sysfs attributes to provide AER stats and breakdown
  PCI/AER: Add sysfs attributes for rootport cumulative stats
