Subject: [PATCH v2 3/3] net: fddi: skfp: Remove unused private PCI definitions

Remove unused and private PCI definitions from skfbi.h because generic PCI
symbols are already included from pci_regs.h.

This comment should be removed because it goes along with the
definitions below (the ones from PCI_VENDOR_ID to PCI_MAX_LAT).

You removed the space at the end of the I2C_ADDR_VPD line. That space
*is* a whitespace error, but generally you should avoid fixing random
unrelated issues in the middle of your patch. Those random fixes make
it harder because the reviewer is expecting to see unused PCI-related
things removed and seeing an I2C diff is surprising and forces him/her
to do some investigation.

These should be replaced by PCI_STATUS_DETECTED_PARITY and similar
generic definitions. You could do this in your 1/1 patch along with
PCI_REVISION_ID.
