[PATCH v1 0/3] PCI: Rename host functions for consistency

[PATCH v1 0/3] PCI: Rename host functions for consistency

[Bjorn Helgaas]

All native host bridge driver probe functions are called *_pci_probe() or
*_pcie_probe() *except* X-Gene's.  All "is the link up?" functions are
called *_pcie_link_up() *except* Altera's and Xilinx's.  Rename them to be
consistent.

I plan to include these for v4.15 unless there are objections.
