There's always some duplication when using such:
for example to override device type, we would need:
pci_word_test_and_clear_mask(cap + PCI_EXP_FLAGS,
PCI_EXP_FLAGS_TYPE
sounds good idea and the patch Looks good.

pci_regs.h specifies many registers by mask +
shifted register values.
There's always some duplication when using such:
for example to override device type, we would need:
pci_word_test_and_clear_mask(cap + PCI_EXP_FLAGS,
PCI_EXP_FLAGS_TYPE);
pci_word_test_and_set_mask(cap + PCI_EXP_FLAGS,
