This change will be visible in the sysfs "broken_parity_status" file, but I doubt that's important. I dropped Leon's reviewed-by because I fiddled with the code. Similarly I haven't added your signed-off-by, Heiner, because I don't want you blamed for my errors. But if this looks OK to you I'll add it. v1: https://lore.kernel.org/r/a6f09e1b-4076-59d1-a4e3-05c5955bfff2@gmail.com v2: https://lore.kernel.org/r/bbc33d9b-af7c-8910-cdb3-fa3e3b2e3266@gmail.com - reduce scope of N2100 change to using the new PCI core quirk v3: https://lore.kernel.org/r/992c800e-2e12-16b0-4845-6311b295d932@gmail.com/ - improve commit message of patch 2 v4: - add pci_disable_parity() (not conditional on CONFIG_PCI_QUIRKS) - remove setting of dev->broken_parity_status Bjorn Helgaas (1): PCI: Add pci_disable_parity() Heiner Kallweit (2): IB/mthca: Disable parity reporting ARM: iop32x: disable N2100 PCI parity reporting arch/arm/mach-iop32x/n2100.c | 8 ++++---- drivers/net/ethernet/realtek/r8169_main.c | 14 -------------- drivers/pci/pci.c | 17 +++++++++++++++++ drivers/pci/quirks.c | 13 ++++--------- include/linux/pci.h | 1 + 5 files changed, 26 insertions(+), 27 deletions(-) Reviewed-by: Krzysztof Wilczyński
