Please include a commit log.  For PCI, the "v2: ..." stuff would go
below the "---" so it doesn't get included in the git commit.  I don't
know what the DRM convention is.

It's OK if the commit log repeats the subject.  The subject is like
the title of a story -- it's not the first sentence of the story.

Please include a spec citation for the PCI_BASE_CLASS_ACCELERATOR
values in the commit log.  I think it's something like "PCI Code and
ID Assignment, r1.9, sec 1, 1.19".
