Subject: [PATCH 0/3] PCI/AER: Fix and optimize usage of status clear api

Hello,

This series contains some fixes and optimizations of aer api usage.
We add some process to clear uncorrectable error status, then add
distinction between fatal and nonfatal situations in pcie_do_recovery()
and reduce some redundant code. The series involves pci driver and
vendor driver.

Thanks,
Zhuo Chen

  PCI/AER: Use pci_aer_clear_uncorrect_error_status() to clear
    uncorrectable error status
  PCI/ERR: Clear fatal status in pcie_do_recovery()
  PCI/AER: Use pci_aer_raw_clear_status() to clear root port's AER error
    status
