[Linux-kernel-mentees] [PATCH v2 0/3] net: fddi: skfp: Use PCI generic definitions instead of private duplicates

[puranjay12]

This patch series removes the private duplicates of PCI definitions in
favour of generic definitions defined in pci_regs.h.

This driver only uses one of the generic PCI definitons, i.e.
PCI_REVISION_ID, which is included from pci_regs.h and its private
version is removed from skfbi.h with all other private defines.

The skfbi.h defines PCI_REV_ID which is renamed to PCI_REVISION_ID in
drvfbi.c to make it compatible with the generic define in pci_regs.h.

We already cache the revision in struct pci_dev.  In doubt you should
use that one.

You removed the blank line between the list of include files and the
SCCS ID (now there's an anachronism) below.  That blank line is part
of typical Linux style and you should keep it.

[Linux-kernel-mentees] [PATCH v2 3/3] net: fddi: skfp: Remove unused private PCI definitions

[puranjay12]

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

[Linux-kernel-mentees] [PATCH v2 3/3] net: fddi: skfp: Remove unused private PCI definitions

[Puranjay Mohan]

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.

Does anyone still have the hardware to test this?
Maybe FDDI should be put out to pasture.
