Subject: [PATCH v4 0/3] PCI: Disable parity checking

I think this is essentially the same as Heiner's v3 posting, with these
changes:

  - Added a pci_disable_parity() interface in pci.c instead of making a
    public pci_quirk_broken_parity() because quirks.c is only compiled when
    CONFIG_PCI_QUIRKS=y.

  - Removed the setting of dev->broken_parity_status because it's really
    only used by EDAC error reporting, and if we disable parity error
    reporting, we shouldn't get there.  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
