Subject: [PATCH v3 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
v3:
- improve commit message of patch 2
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
