The PCI-to-PCI Bridge Architecture Specification defines a secondary
interface (commonly known as a secondary bus) as "The PCI interface of the
bridge that is connected to the PCI bus farthest from the CPU is referred
to as the secondary PCI interface."
The term subordinate bus number is used to define "the bus number of the
highest numbered PCI bus segment which is behind (or subordinate to) the
bridge".
The current code tree mixes up these terms such that pci_dev->subordinate
is really the secondary interface. This gets confusing as other areas
of the code use proper terminology for subordinate and secondary.
This is a cleanup that renames pci_dev->subordinate to pci_dev->secondary,
and cleans up some comments referring to the secondary and subordinate
busses.
There are some additional style cleanups that were pointed out by checkpatch.pl.
