[PATCH 3/5] PCI: Move pci_dev_is/assign_added() to pci.h

Niklas Schnelle
2021-09-06T09:49:45Z

The helper function pci_dev_is_added() from drivers/pci/pci.h is used in
PCI arch code of both s390 and powerpc leading to awkward relative
includes. Move it to the global include/linux/pci.h and get rid of these
includes just for that one function.
