    Subject[PATCH 5.10 059/545] PCI: Add defines for normal and subtractive PCI bridges
    Date
    From: Pali Rohár <pali@kernel.org>

    commit 904b10fb189cc15376e9bfce1ef0282e68b0b004 upstream.

    Add these PCI class codes to pci_ids.h:

    PCI_CLASS_BRIDGE_PCI_NORMAL
    PCI_CLASS_BRIDGE_PCI_SUBTRACTIVE

    Use these defines in all kernel code for describing PCI class codes for
    normal and subtractive PCI bridges.

    [bhelgaas: similar change in pci-mvebu.c]
