We could add such a definition and use it the same way PCI_SRIOV_NUM_BARS is used. There is already the definition PCI_BAR_COUNT for s390 only. Thus, this patchset introduces it globally. The patch is splitted into 7 parts for different drivers/subsystems for easy readability. Denis Efremov (7): PCI: Add define for the number of standard PCI BARs s390/pci: Replace PCI_BAR_COUNT with PCI_STD_NUM_BARS x86/PCI: Use PCI_STD_NUM_BARS in loops instead of PCI_STD_RESOURCE_END PCI/net: Use PCI_STD_NUM_BARS in loops instead of PCI_STD_RESOURCE_END rapidio/tsi721: use PCI_STD_NUM_BARS in loops instead of PCI_STD_RESOURCE_END efifb: Use PCI_STD_NUM_BARS in loops instead of PCI_STD_RESOURCE_END vfio_pci: Use PCI_STD_NUM_BARS in loops instead of PCI_STD_RESOURCE_END arch/s390/include/asm/pci.h | 5 +---- arch/s390/include/asm/pci_clp.h | 6 +++--- arch/s390/pci/pci.c | 16 ++++++++-------- arch/s390/pci/pci_clp.c | 6 +++--- arch/x86/pci/common.c | 2 +- drivers/net/ethernet/stmicro/stmmac/stmmac_pci.c | 4 ++-- drivers/net/ethernet/synopsys/dwc-xlgmac-pci.c | 2 +- drivers/pci/quirks.c | 2 +- drivers/rapidio/devices/tsi721.c | 2 +- drivers/vfio/pci/vfio_pci.c | 4 ++-- drivers/vfio/pci/vfio_pci_config.c | 2 +- drivers/vfio/pci/vfio_pci_private.h | 4 ++-- drivers/video/fbdev/efifb.c | 2 +- include/linux/pci.h | 2 +- include/uapi/linux/pci_regs.h | 1 + 15 files changed, 29 insertions(+), 31 deletions(-) -- 2.21.0
