Subject: [PATCH v2 0/3] PCI: Disable parity checking if broken_parity is set

If we know that a device has broken parity checking, then disable it.
This avoids quirks like in r8169 where on the first parity error
interrupt parity checking will be disabled if broken_parity_status
is set. Make pci_quirk_broken_parity() public so that it can be used
by platform code, e.g. for Thecus N2100.

v2:
- reduce scope of N2100 change to using the new PCI core quirk

Heiner Kallweit (3):
  PCI: Disable parity checking if broken_parity_status is set
  ARM: iop32x: improve N2100 PCI broken parity quirk
  r8169: simplify broken parity handling now that PCI core takes care
