Regarding the suggestion above - it has been like that initially, albeit Bjorn suggested that there is no need to reply on the macros that use PCI_SLOT() and PCI_FUNC() macros, see: https://lore.kernel.org/linux-pci/20200922232715.GA2238688@bjorn-Precision-5520/ I would be happy to put the macros back if there is a value in having the extra macros added - perhaps for clarify, as you suggest.
