If you edit this patch to add my ack or for other reasons,
s/conist/const/ above.  The "-v2-" text doesn't need to be in the
changelog, so you can omit it completely, or put it after a line
containing only "---".  I also conventionally capitalize the first
word of the change summary ("Expose") here; run "git log --oneline
drivers/pci/" to see samples.

But don't respin these patches just for that :)
