Maybe just:

PCI: hv: Make functions static

since we already know it's in pci-hyperv.c, and it's obvious that you
can only do this for functions that are only used locally.

Rewrap commit log to fill 75 columns.

Does this fix all the similar warnings in drivers/pci/? If there are
more, maybe we could fix them all in a single patch or at least a
single series?
